Air Purifier

What is a Air Purifier

An air purifier is a compact device that removes dust, smoke, pet hair and dander, harmful allergens and various other floating impurities from the air. It ensures that the air you breathe is pure.

How Air purifiers work?

The core component or technology of the air purifier is the filter. The filter is like a mesh which blocks the harmful particles and bacteria and allow the air to pass. So essentially the filters clean the air, the rest of the machine does take care of air inflow and outflow. The inflow and outflow rate depends on blower and filter capacity to purify the air. Thats it. In other words you are selecting the filter and add-on features.

Why a good Air Purifier is required?

The polluted times we live in, air purifiers for homes are no longer considered a luxury. It has now become a necessity—pretty much as essential as food, water and air. Using an air purifier will help create cleaner, healthier air in your home or office, so you can enjoy better indoor air quality.

Best Air Purifier | Buying Guide : Things to consider while buying a Home Air Purifier

An air purifier has to be the right fit for the room space. The best way of going about it is to match the size of your room and the coverage area of each purifier—this is usually mentioned in square feet (sq. ft). Buying one that is too small for your room will mean that the purifier will be unable to clean the air completely and also keep it clean constantly.

Filter Types

Every filter technology has the same goal – to filter the air of dust, pollen, odors, smoke and other harmful pollutants. There are different types of air cleaning technologies that you can choose from.

HEPA (High Efficiency Particulate Air) Filters efficiently clean allergens such as pollen, animal skin and dander, mold spores, and dust. HEPA filters remove at least 99.9% of all the particles as small as 0.3 microns.

  • HEPA air purifier filters have to be periodically changed.
  • HEPA certified filters work well for all common particle allergens, but remember not all HEPA filters are created equal.
  • The larger the HEPA filter, the more particulate it will be able to remove. The size, material, and construction of the actual filter plays a vital role in the air purifier’s performance.

Activated Carbon Filters are rarely used by themselves, but are often used in combination with other filters. Activated carbon/charcoal filters help in absorbing odors and gases thereby neutralizing smoke, chemicals, and fumes.

  • Reacts with oxygen to open up millions of pores that are capable of trapping a large amount of gas and odor.
  • This makes it the ideal surface for bonding with chemical or vapour molecules.
  • Needs to be replaced once they are saturated for optimal performance.

Antibacterial and Germicidal Filters help in eliminating harmful bacteria and germs.

  • Using UV filters along with HEPA filters ensures the air you breathe is sterile.
  • Used in hospitals, kitchens, labs and daycare schools to minimize the risk of airborne infections.

Charged Media Filters combine a particle filter along with an electrostatic charge filter to capture particles as small as 0.1 microns. They are very efficient in purifying air, but need to be replaced fairly regularly to ensure optimal performance.

Photocatalytic Oxidation (PCO) makes use of a titanium dioxide coated metal plate along with UV light to oxidize and physically break down chemicals during the filtration process.

By doing so larger molecules break down into harmless carbon dioxide and water molecules.

Electrostatic Precipitators function just like charged media filters but instead of using filters to capture particles, the particles precipitate and accumulate on the collector plates.

These plates can be washed clean and do not need to be replaced.

Ion and Ozone Generators clean the air by forcing impurities to cling to nearby surfaces.

The negative ions combine with impurities such as dust and smoke particles and stick to walls and carpets. They may create dirty spots on these surfaces which need to be cleaned.

Pre-Filters, like foam and non-woven polyester, eliminate large particles like pet hair before the next stage of filtration.

  • Some have electrostatic properties and use activated carbon to improve filtration and also remove odors and smoke.
  • They need to be replaced regularly to increase the air purifiers lifespan.

Coverage Area

Make sure the square footage listed for the air purifier is about the same or slightly greater than the square footage of the room where you intend to use it. Square footage numbers are calculated based on an 8′ ceiling, CFM, and a stated number of air exchanges per hour.

Air Changes Per Hour (ACH)

This number, also known as the ACH rating, tells us how frequently the air purifier can exchange all the air in a given room. For example, if the purifier has a ACH rating of 6 for a 20′ x 20′ room, then it is capable of exchanging all of the air in that room 6 times every hour. If you have allergies or asthma, you want an ACH rating of at least 4 and preferably 6 or 8.


HEPA air purifiers range from affordable air purifiers for small spaces to fully loaded air purifiers for large rooms. Initial cost isn’t the only expense related to operating an air purifier. Also consider how much replacement filters will cost annually. For some energy usage may also be a concern. While most use little energy, some are Energy Star rated.

Filter Replacements

If you are buying a HEPA air purifier, don’t forget to check and see how much replacement filters will cost. If your unit includes both a HEPA filter and a carbon filter or other combination filtration media, they may need to be replaced separately and after different periods of time. Regular filter replacement is key to getting to the most of your investment while minimizing wear on the motor. Additionally, some manufacturers require regular filter replacement as a condition of their warranty.

Energy Usage

Like all appliances, different air purifiers use different amounts of energy. Unlike most appliances though, air purifiers run, or should run, continuously, so you may want to consider your utility bill before buying an air purifier. If only volts and amps are listed, simply multiply the two: volts x amps = watts. And to determine how many kilowatt hours your model uses per day, multiple watt x hours then divide that by 1000. This will give you daily kilowatt hour usage. Typical air cleaners can use anywhere from 50 watts on low to 200 watts on high. (For comparison sake, a typical lamp uses about 60 watts, while a typical computer uses about 300 watts).

Noise Level

Some air purifiers, like Blueair and AirPura, are extremely quiet while nearly all can be quite loud when operating at full power. For models with thick carbon filters, a slower fan speed can actually produce better filtration results. A fan moving too slowly may not be pushing enough air to properly clean the room. It can be a bit of a balancing act when it comes to noise, but in general, there are appropriate fan settings with comfortable noise levels on all air purifiers. If possible, ask for a demonstration before you buy your air purifier. If you live near the Atlanta area, we’d be glad to give you a demonstration in our showroom.

Clean Air Delivery Rate (CADR)

Despite flaws with the CADR, this test can give results to help compare air purifiers. While not all manufacturers submit their products for testing, the CADR can be helpful with an apples to apples comparison between models.

Air Pollution

Some air purifiers pollute the air with ozone, a powerful lung irritant that is especially dangerous for asthmatics, children, and the elderly. Avoid these. Look for air purifiers that are CARB certified (California Air Resource Board). CARB is the most stringent testing agency of consumer products, and if you’re unsure, just ask!

Extra Features

These are the bells and whistles. They can make your air purifier a lot easier to use or simply be an added expense that seem useful but really aren’t. This is a bit of a balancing act. For example, a filter change indicator light lets you know when to change the filter, and handles or casters are important if you plan on moving your air purifier frequently. What about audible reminders, LCD screens, or backlights?

Washable Prefilters

The reusable filters collect large particles before they reach the primary filter, potentially extending its life and saving you money on filters.

There is no single air purifier that’s right for everyone. When you’re shopping for an air purifier, always look first at the CADR ratings and filter types to get an idea of how effective the air purifier will be for your specific needs.

Once you’ve identified an air purifier that offers the best filtration for common pollutants in your home and that is the right size for your space, evaluate secondary features like noise levels and portability. Also make sure that the air purifier’s energy costs and ongoing maintenance costs are within your budget.
