Before I share my views on the Best Air Purifier for Allergies and Asthma available in the market, I would like to dive a bit deep into the topic and discuss more on Air Purifier. There are lots of purifier being marketed but most of them cannot be classified as the Best Air Purifier For Allergies And Asthma Patients. One must know the exact requirement before buying the Air purifier for Home. I hope this post will help you in your buying decision.
What is an Air Purifier and How does it work?
An air purifier is an equipment used to remove contamination like Dust, Dust millets or Mold Spores from the air in a room. These types of equipment are promoted in the market as being beneficial for the patients of Allergies and Asthma. Air purifiers are also used to remove the bad odor in the rooms. They are also recommended for eliminating passive tobacco smoke. Air purifier for your home may be very compact and “small in size” depending upon the size of the room whereas commercial air purifier may either be small stand-alone units or larger units affixed to AHU (Air handler units)
Are the Air Purifier Really Effective?
Frankly speaking, no effective research has been conducted in this matter and as no scientific data is available. But Doctors and medical experts both agree that these machines do provide clean filtered air which is what people are looking for.
But the experts have a different conflicting opinion on the Ionic Air purifiers using Ozone as purifying Agent. In my opinion, exposure to a higher concentration of Ozone for a longer period may have an impact on health and can cause throat irritation and chest infection.
Even EPA, United States Environmental Protection Agency do not recommend Ozone generators.
Therefore I would advise using non-Ionic Air purifiers mainly with HEPA Filters.
How to select the right Capacity Air Purifier?
The right Air purifier for your room would be one which can completely clean the air in your room.
You would like to have a very high-efficiency filter which lasts without a performance dip. But then you also need to replace the air in the room.
Clean Air Delivery Rate or CADR rating is an industry-standard developed by the Association of Home Appliances Manufacturers (AHAM) to measure the amount of clean air flowing out of the air purifier. AHAM is the leading agency in setting up the room Air purifier standards.
To select the right Air purifier, you must also know the square cubic meter volume of your room. In most of the situation, you want to change air minimum 2 to 5 times. That means you would like to change the air in the room every 12 minutes to 30 minutes.

Type Of Air Purifiers
You may find a variety of Air Purifiers available in the market. The most prominent of the options are:
- Activated Carbon Air Filters based Air Purifiers.
- UV Air Purifiers.
- Ionic Air Purifiers.
Which Filter is best for my Allergies?
HEPA stands for high-efficiency particulate Arrestance. Any air filter which remover at least 99.97 percent of particles larger than .3 microns are classified as HEPA.
You can choose any of the following HEPA Air purifier based on your RequirementTrue HEPA/UV-C Air Purifiers :
True HEPA/UV-C air purifiers are the best air purifiers in the market helpful in highly allergen regions and are people who are very sensitive to allergic reactions. However these are expensive Air purifiers and if money is not the constraint, you may give preference to these Air Purifiers. These Air purifiers are the combination of HEPA filters and UV technology
True Hepa Air Purifiers are without UV protection and use replaceable HEPA-rated filters to remove 99.97 percent of the airborne particles. True HEPA air purifier is the minimum standard recommended for Allergic patients. They are cheaper than the True HEPA/UV-C air purifiers.
True HEPA air purifiers can be employed if Dust mites and pollen aren’t major considerations. HEPA type air purifiers are much economical to buy but can only arrest 99 % of small airborne particles like smoke or dust particles. But airborne particles like dust millets and Poolen which are responsible for causing allergies may not be removed from the air in your room.
Permanent HEPA-Type Air Purifiers
These are similar to HEPA-Type air purifiers with the only difference that the filters are not replaceable. These reusable filters require more attention and repeated cleaning to be effective.
