Choosing The Best Filter In Air Purifiers To Battle Allergies Effectively

Both the American Lung Association and the US Environmental Protection Agency (EPA) have approved that people who suffer from allergies may find adequate relief by using air purifiers. In this article we will look at different types of air filters and rank them according to how affective they are in dealing with this persistent problem. So let’s look at all the possibilities and see for ourselves which fits the need the most:

Mechanical Filters

The most effective filters in this category are air purifiers  that utilize HEPA filters. The working mechanism of these filters is based on trapping harmful particles such as dust, mites, pet dander, pollen, and tobacco smoke, among others using a fine mesh.

However, even though the filter might help in reducing the contaminant count in breathable , even then it’s not a complete solution. The following helping tips are necessary for it to be completely effective:

  • Keep the area of your place of residence or work clean
  • Vacuum frequently
  • Replace carpets with flooring of vinyl or wood
  • Keep pets outdoors and away from your sleeping zones
  • Change bed sheets frequently and wash them with hot water
  • If possible cover your pillows and mattresses with plastic (Ouch!)

Electronic Filters

All electronic filters are able to use electrical charges to attract irritants and allergens. But the debate over here is, are they really that effective as other conventional filters? Here are the pros:

  • They are washable filters, so you don’t need to buy a new one
  • They are quite attractively priced

On the other hand, let’s look at the cons:

  • Their ability to filter air is considerably less when compared to other filters used in air purifiers
  • With years of use, they often make your room smell like a gym or a locker room, even providing an organic substrate where mold and mildew can grow over time
  • They block air more than other air filters, essentially making your conditioning system work twice as hard and many users calling for maintenance issues after prolonged use


Hybrid Filters

As the name suggests, these filters combine the advantages of both mechanical and electrostatic filters while overcoming most of their disadvantages.

Ozone Generators

Not recommended by authorities, these devices create a layer of ozone to clean air. It’s use is considered a health related concern by the American Lung Association. A device is only suitable if it can ensure high efficiency over longer periods of time and produce ozone levels not above 0.05 parts per million to be considered safe.


When it comes to fighting allergies, the best choice is to use a hybrid filter, which offers a HEPA filter and other technologies working hand in hand to ensure the best possible filtration process as possible. Another thing that buyers should focus on is the CADR (Clean Air Delivery Rate), the higher the CADR, the faster the unit filters air.
