  • Odor, dust and allergen sensors let you know when certain pollutants are detected, such as cigarette smoke, chemicals, dust mites, pollen, pet dander, mold spores and many more.
  • The clean air monitor tells you how clean or polluted the air is, removing the guesswork.
  • Select "Automatic" mode to maximize performance and energy savings, while keeping sound level as low as needed. Fan speed is automatically adjusted according to pollution level.
  • Diagnostic sensors indicate when to replace filters, and when to clean the metal dust collector grid.
  • The UV light and negative ion indicators let you know that these functions are working, and indicate when the UV lamp needs to be replaced, so it is not left in too long or replaced prematurely.

The washable pre filter does not require replacement, and enhances the durability and performance of the other filters. Pre-filters are recommended by the Dept. of Homeland Security.

Electrostatically-charged dust collection grid effectively traps charged particles & pollutants like a magnet. Simply wipe clean when dirty. In a study by the Canada Mortgage and Housing Corporation, electrostatic precipitation was found to be the more effective in purifying the air than any other filter type.

Activated carbon filter traps chemicals, gases and odors. Recommended by the Centers of Disease Control, Dept. of Health and Human Services and the National Institute of Occupational Safety and Health.

Long-lasting, high-efficiency HEPA filter - most effective way to capture dust and allergens. Recommended by the Dept. of Homeland Security and Centers of Disease Control.

Photocatalytic oxidation (TiO2) filter which effectively reduces chemicals, bacteria and odors. Found to be highly effective in tests commissioned by the U.S. Dept. of Energy.

Germicidal UV lamp destroys micro-organisms. Recommended by the Centers of Disease Control and the Air Institute of Respiratory Education.

Air-cleaning negative ions are circulated throughout the room. Completely safe (virtually no ozone), and scientifically proven to be effective and to enhance filter efficiency. Found to be highly effective in multiple U.S. Dept. of Agriculture studies.

The Multiple Air Inlet Design enables maximum air flow through the unit. The powerful, yet quiet fan accelerates the purified air throughout the room.

Economical. The Intelli-Pro is energy efficient, and uses sensor technology to reduce electricity usage. Offers low-cost replacement filter and UV lamp.

Quiet. Features "Quiet" setting to maintain peace and tranquility in room. Still fairly quiet even on "High" setting though.

What Sensor Technology Does for You:

Odor, Dust & Allergen Sensors -
Know which airborne pollutants are present.

The Intelli-Pro has sensors to detect odors (such as chemicals and cigarette smoke), dust and allergens (such as pollen, pet dander, ragweed and mold spores). There is an LED indicator light for each of these pollutant types. If odors are detected, the "Odor" indicator light on the control panel will become lit. The same for dust and allergens.

Clean Air Monitor -
Know just how clean or polluted the air really is.

The Intelli-Pro senses just how clean or polluted the air really is, and conveys this information through the four LED indicator lights. The dirtier the air, the more indicator lights that are lit. For example, if all four indicator lights are lit, the air is very polluted. If only one is lit, the air is very clean.

Automatic Mode -
Saves you money on your electric bill by automatically adjusting settings.

In this mode, the Intelli-Pro will automatically adjust the settings of the air purifier according to how clean or polluted the air is. For example, if the air is detected to be polluted, it will run the fan on a higher setting. On the other hand, if the air is determined to be sufficiently clean, it will run the fan on the lowest setting ("Quiet") in order to use less electricity, saving you money on your electric bill.

Filter Replace/Maintenance Indicators -
Take the guesswork out of knowing when to replace filters.

The Intelli-Pro takes the guesswork out of trying to determine when to replace filters and when to wipe the metal dust collector plates clean. The filter sensor lets you know when it is time to replace the HEPA/activated carbon filter. This way, you do not replace it too soon (saving you money), and not too late, when it becomes saturated to the point it begins releasing captured contaminates back into the air.

Ion/UV Light Indicator -
Now you can know the ionizer and UV lamp are working properly.

This sensor verifies the ionizer and UV lamp are working properly. Without these sensors, it is very difficult to know if UV lamps and ionizers are fully operational, since there are few visual or audio signs to verify this. When they are both working properly, the blue light under "Ion/UV Indicator" will go back and forth between dim and bright.

How the Intelli-Pro Purifies the Air:

Washable Pre Filter. The air first enters pre filter, capturing the largest particles, which enhances the durability and performance of the other filters.

Washable Dust Collector Plates. The electrostatically-charged dust collector grid traps particles and pollutants like a magnet. This is similar to Friedrich C-90A, which has been Consumer Reports top-rated air purifier. Unlike the C-90A, the Intelli-Pro has multiple other leading technologies. In a study by the Canada Mortgage and Housing Corporation, electrostatic precipitation was found to be more effective in purifying the air than any other filter type.

Activated Carbon Filter. The best type of air filter for trapping chemicals, gases, odors and cigarette smoke. According to Penn State Dept. of Aerobiological researchers, carbon filters serve to remove odors, volatile organic compounds (VOCs) and chemicals that other filters cannot.

High-Efficiency HEPA Filter. The most effective type of air filter at capturing dust, allergens and other solid particles (including bacteria). HEPA filters are recommended by the U.S. Department of Homeland Security.

Photocatalytic Oxidation (TiO2) Filter. This filter is coated with titanium dioxide, which produces highly reactive ions and electrons when combined with the UV light from the Intelli-Pro's UV lamp. These highly reactive ions attach to chemical molecules, bacteria and odor-causing compounds, destroying them through oxidation. Independent tests by research scientists have proven photocatalytic oxidation to be highly effective.

Germicidal UV Lamp. The most effective way to destroy micro-organisms, such as germs, viruses, fungi (such as mold) and bacteria. Also destroys micro-organisms including those that are trapped by the HEPA air filter, preventing them from reproducing and recirculating through the room. UV lamps are recommended by the U.S. Centers of Disease Control. Also disinfects the micro-organisms that are trapped in the HEPA filter, which is why the CDC recommends using a germicidal UV lamp and HEPA air filter together.

Safe and Effective Ionizer. Circulates trillions of negative ions to neutralize floating pollutants throughout the room. A Journal of Hygiene study found negative ions to improve efficiency of filter units, and multiple studies (including those by the U.S. Dept. of Agriculture) have found ionizers to be highly effective against dust, bacteria, etc. Finally, the Intelli-Pro ionizer is proven to be safe, producing virtually no ozone whatsoever.

Just some of the many types of pollutants removed by the Intelli-Pro:

Dust/Dust Mites. The Hepa air filter in the Intelli-Pro is highly effective at capturing solid particles such as dust and dust mites. According to the Journal of Hygiene, ionizers help to increase the efficiency of filters by causing airborne particles to conglomerate, making them easier to capture in the filtration material. The dust collector grid also helps with dust and mites, which are magnetically bonded to the electrostatically-charged metal plates. The plates are periodically wiped clean, and do not require replacement. Plus, negative ions also cause airborne particles to precipitate out of the air you breathe, and have been found to be extremely effective at controlling dust without the presence of a filter, through studies conducted by the U.S. Dept. of Agriculture. UV light can be deadly for dust mites.

Bacteria. Much of the bacteria floating around in the air can be effectively captured by the Hepa air filter, while the germicidal UV lamp serves to disinfect the bacteria trapped by the Hepa filter. Plus, according to studies by the U.S. Dept. of Agriculture, negative ion-producing ionizers are extremely effective at reducing airborne bacteria. The Intelli-Pro also includes a photocatalytic oxidation filter, which have been proven effective at destroying bacteria. The dust collector grid also helps to remove bacteria from the air.

Pollen and Other Allergens. Hepa air filters are the most commonly recommended filter for allergens, and are generally considered the most effective type against them. Negative ion-producing ionizers increase the efficiency of filters by causing airborne particles to conglomerate, making them easier to capture. Plus, negative ions also cause airborne particles to precipitate out of the air you breathe. The dust collector grid will also help to remove allergens from the air, which are magnetically bonded to the electrostatically-charged metal plates. Simply wipe them clean periodically and they will never require replacement.

Mold/Fungi. Mold spores are effectively captured by Hepa air filters, especially with the help of negative ion-producing ionizers. UV light is deadly against the microbiological toxins associated with mold. The activated carbon filtration and photocatalytic oxidation technologies used by the Intelli-Pro are effective against mildew smells often emitted by household molds.

Cigarette Smoke. The carbon air filter in the Intelli-Pro absorbs smoke particles and the toxic chemicals associated with cigarette smoke. With the help of the photocatalytic oxidation filter, it also helps to reduce or eliminate odors from cigarette smoke. The negative ions also remove smoke particles from air.

Chemicals and VOCs (Volatile Organic Compounds). The carbon air filter is very effective at absorbing chemicals and gases. Also, photocatalytic oxidation has been proven effective at breaking up chemical compounds. Furthermore, the ionizer also helps to neutralize chemical fumes.

Germs/Viruses. The UV light is deadly against micro-organisms such as germs and viruses, and highly effective at destroying them as they pass by the UV lamp. Negative ions have also been known to help to neutralize viruses.

Odors. Both the photocatalytic oxidation filter and activated carbon air filter are effective at eliminating or reducing strong odors.

Carbon Monoxide. A statistically significant decrease of CO values was found with an ionizer activated. This was discovered by researchers at Brompton Hospital in London, and published in European Respiratory Journal.

Clinical Test Results:
Intelli-Pro outperformed the Consumer Reports top-rated air purifier along with other popular air purifiers.

Removal Rates During Clinical Testing:

Air Purifier Model Hydrogen Sulfide Test Particle Removal Test

Note 1: All air purifier models were tested on "high" setting for the hydrogen sulfide test.
Note 2: All air purifier models were tested on "high" setting for the particle removal test, except the Friedrich C-90A. This model was tested on the "low" setting, since its low setting was more comparable to the other models on "high" in terms of noise and fan speed. Due to the noise of the C-90A on "high", users would likely operate it on "low" most of the time.

About Hydrogen Sulfide. H2S is a strong gas created by stagnant sewage, and is one of the very worst, and most difficult-to-remove pollutants known to man. An air purifiers ability to remove H2S is a good indication of its ability to remove strong odors, odor-causing toxins and volatile organic chemicals (VOCs).

Aspergillus Mold Test.
The ability of the Intelli-Pro to kill aspergillus mold was also tested. In one hour of time, the Intelli-Pro successfully destroyed 100% of the aspergillus mold cultures. Aspergillus is one of the most toxic and allergenic types of indoor mold.

Do Surround Air-brand air purifiers produce ozone?

With the exception of the XJ-3000 series, Surround Air-brand air purifiers produce virtually no ozone, far beneath the recommended levels set by the FDA, the UL and the California State Air Resource Board (CARB). The Multi-Tech XJ-3000C and XJ-3000D models have a programmable sanitizer function that can be turned on or off. But even with these two models produce ozone levels that are well within the 50ppb guidelines with the sanitizer turned on to the highest setting. Both have been tested and certified with the UL and the state of California for electrical and ozone safety.

How do I know how much area I have?

Measure the length and width of the room and then multiply them together. This will give you the square footage of the room. For example a 20 x 30 room is 600 Sq. Ft.

Determining square footage coverage for an air purifier is not an exact science though, since there are many factors that will influence the amount of square footage an air purifier will cover.

The Association of Home Appliance Manufacturers (AHAM) developed the CADR system (Clean Air Delivery Rate) in an attempt to create a standard for square footage coverage, but this methodology does not take all pertinent factors into account.

Surround Air ratings are based on multiple factors, such as fan power, ratings of comparable models, and the types of technologies used (such as air ionization). With air ionization, negative ions are circulated into the air and throughout the room if adequate air flow is present, increasing the amount of square footage that can be covered.

It should also be noted that the closer you are to the air purifier, the more efficiently the air at that distance will be purified, regardless of an air purifier's square footage rating. The areas at the outer extent of an air purifier's effective coverage area will not be purified as thoroughly as the areas closer to the unit.

Keep in mind that the square footage ratings offered by Surround Air are merely a guide, and not to be completely relied upon. Once in your home, there are several factors that can influence the amount of square footage an air purifier will effectively cover, such as:

  • Pollution Level. The higher the pollution level, the lower the effective coverage area.

  • Air Flow. The greater the air flow in an indoor area, the higher the effective coverage area.

  • Floor Plan Layout. The more open the floor plan, the higher the effective coverage area.

  • Air Purification Technologies. With filters, the air must pass through the filter in order to be purified. With air ionization, negative ions are circulated through the room.

What if my room is larger than the size covered by the air purifier?

Even if placed in a room larger than its square-footage rating, an air purifier can still help improve air quality beyond the area it is designed to cover if the room is open. This is especially true if there is good air flow and the pollution/allergenic level is not heavier than typical. The air in open spaces naturally circulates over time, and some of the pockets of air farther away from the air purifier may eventually shift into its sphere of coverage. You can also move the air purifier between locations to ensure broader coverage. But for optimal results, we would recommend buying multiple air purifiers to cover spaces larger than what it is rated for.

What is a CADR Rating?

CADR stands for "Clean Air Delivery Rate", which is a measurement method developed by the Association of Home Appliance Manufacturers (AHAM) in an attempt to institute a common standard by which to evaluate air purifiers. It is expressed as a square footage rating, based on particles removed at various size ranges, multiplied by the fan speed of the air purifier. However, the CADR testing method is controversial for several reasons. In which case, Surround Air uses the straight-forward air chamber test to determine the effectiveness of its air purifier models.

CADR is completely irrelevant for some of the pollutants people are most interested in removing, such as micro-organisms, chemicals and odors. The CADR testing method measures only solid particles.

In addition to ultra-fine particles, Surround Air also tests for the ability to inhibit mold cultures and to remove hydrogen sulfide. Hydrogen sulfide is one of the very worst, and most difficult-to-remove pollutants known to man. An air purifier's ability to remove H2S is a good indication of its ability to remove strong odors and volatile organic chemicals (VOCs).

Air chamber testing is straight forward, measuring the air purifier's ability to remove the pollutants present in the chamber. CADR is theoretical, factoring air flow and absorbability of the filter material.

As a result, CADR favors air purifiers with the strongest fans and thickest filtration media. In other words, it is geared toward more expensive and loud air purifiers that consume high amounts of power and energy, with expensive replacement filters.

In reality, air purifier users value low-noise models that use modest amounts of energy, with low replacement costs. In which case, the trick is to produce an air purifier that is effective, yet meets the demands of customers who do not want an overly expensive and disruptive air purifier.

Air chamber testing helps determine if a quieter, energy efficient air purifier featuring non-filter technologies is effective, in order to create a capable, yet user-friendly product to meet the demands of the consumer.

What is the Air Volume of my unit?

The amount of air that is circulated throughout the room depends on what the CFM (Cubic Feet per Minute) measurement is for the unit. Each unit we offer has a different CFM output that ranges anywhere from 31cfm to 180cfm when running the fan on the highest setting.

Is this machine safe to use around pets?

All of our units effectively remove pet dander and are completely safe to use around pets of any kind.

How much energy will my unit use?

The power consumption of each machine is calculated by the Wattage of each unit. The bigger the unit, the more energy it requires. The Wattage of our units range anywhere from 40 Watts to 80 Watts. This would equate to about $30-$60 in annual electricity costs if run continuously throughout the year, based on average cost per kilowatt-hour in the U.S. Many of the units that are touted for effectiveness, especially in CADR ratings, draw far higher amounts of electricity to operate, due to ultra-thick filters and over-sized fan motors in order to achieve maximum air movement. But with innovate air-cleaning technologies such as ionization and photocatalytic oxidation, Surround Air-brand air purifiers minimize power consumption while optimizing effectiveness.

What are the yearly replacement costs for my air purifier?

Surround Air-brand air purifiers are designed to keep replacement costs low. But the most effective air purifiers utilize technologies such as HEPA and carbon filtration, along with germ-killing UV purification, which require periodic replacement in order to maintain their performance. HEPA/Carbon filters will typically last about 12 months under normal conditions, and replacement filters range from $24 to $44. Most UV lamps should be replaced every 12 months as well, although a few of our models have lamps that will last more than 3 years, and the IP3 lamps (16 mini-LED lamps) do not require replacement. Photocatalytic oxidation filters will typically last 3-5 years. Taking all of this into consideration, Surround Air-brand air purifiers will typically cost $24 to $57 per year in replacement costs.

How shall I know when to replace the filter?

The HEPA/Carbon combination filters will typically last a year in normal environments, and under normal conditions. If there is a smoker in the house, you should replace it every 6-9 months. In a highly sanitary environment, you could probably get away with replacing the filter every 14-18 months. Some of our models include Filter-Replacement Indicators, which will begin blinking when it is time to replace the filter. But these are more of a guide than an absolute diagnostic barometer.

The best way to determine if it is time to replace the filter is to inspect the white, pleated side of the filter. When it is brand new it will be bright white, as it fills with contaminants it will turn gray, or even brown, in color. You can use the nozzle attachment of your vacuum to remove the dust that builds up on the surface of both sides of the filter. But over time, the white HEPA side will become gradually darker in color. You can hold a new sheet of computer paper next to it for reference. Once it becomes persistently gray in color, even after vacuum cleanings, it is time to replace the filter.

How do I change my filter or UV lamp?

Each air purifier's product manual shows how to replace filters and lamps with detailed, step-by-step instructions and diagrams. You can download product manuals here.
