If you are plagued by allergies and/or asthma, you may be considering purchasing a home air filtration system. Air filtration is frequently recommended as a component of environmental control measures for patients with allergic respiratory disease. Allergy elimination is removing the allergy-causing substance in your home.



The primary function of an air cleaner is its ability to remove airborne particles effectively. Air purifiers are devices that are created to clean the air in your house and make the quality of the air you and your family breathe better. Nowadays you can find any air purifier.

An ionizer for house is a great device to get rid of allergens.

What claims they make:

  • Captures viruses
  • Sanitizes the air
  • Destroys mold
  • Medical HEPA
  • Destroys dust mites
  • True HEPA
  • HEPA-like

Moreover, an air cleaner will help allergies if it is environmental and you have the certain type of purifier for the size of the space to use in.

An Air Purifier and Indoor Environmental Allergies

The reasons for indoor environmental allergies are:

  • Dust
  • Tobacco smoke
  • Cockroaches
  • Dust mites
  • Pet allergens
  • Molds

Air purifiers can also eliminate smoke, VOCs, and odors that can cause difficulties in breathing. Air purifiers can also help people with pollen and seasonal allergies.

Allergens fly in the air, fall on surfaces. Pollen doesn’t stay airborne very long, it quickly settles to the ground. Only the floating particles are inhaled. When we move and pick things and furniture up we send them into the air again to float and fall again.

That’s especially important in the winter when people keep their windows and doors closed to trap heat inside.

Air purifiers grab the allergens when they are flying and capture them. This way, they don’t have a chance to circulate in the air again.

An Air Purifier and the Right Room

Here’s one important fact. An air cleaner can’t help with allergies when it is in the room where you spend a lot of time. So, if you want to have the most benefit from your device, put it in this space. One-third of our entire life we spend asleep.

Many people spend more time in the bedroom than in the kitchen, bathroom, on the couch or anywhere else. This way, an air purifier can help with allergies if you put it in the bedroom. Air cleaners tend to be more efficient at pulling things out of the air at table height.

The Right Type of An Air Purifier for Allergies

There are many ways to make the air cleaner. Some of them work for removing allergens, but some air purifiers were not very good at removing allergies.

  • Ozone break down odors, oxidizes VOCs, and kill germs, but it irritates the lungs. An air cleaner creating ozone can make your problems with lungs worse. Some people believe in the cleaning benefits of ozone, but air-quality experts advise avoiding ozone purifiers. An air cleaner producing ozone can’t help allergies.
  • Ultraviolet light destroys bacteria by destroying their DNA, nucleic acids, and their function in the cellular area. It is highly effective with usage for a long and continuous period of time. UV is usually built into air cleaners for killing bacteria, but it will only work if allergens are continuously exposed to the light. It doesn’t eliminate the dead organism. But ultraviolet light doesn’t eliminate particles from the air and it does not work in cleaning a moving air stream.  An air purifier using only UV light can’t help with allergies.
  • Mechanical filters force air through a special screen that captures particles including allergens like pollen, pet dander, dust mites, and tobacco smoke.
  • HEPA filters are one of the best ways to remove allergens. It is a measurement. 99.97% of all particles at 0.3 microns or larger are captured or stopped. That includes common allergens from dust, pet dander, pollen, and mold, which are little enough to get trapped in your lungs. A filter grabs dust and its mites, pet fur, molds and dander, cockroach bits, and any stray pollen hitching a ride inside. HEPA filter is perfect for cleaning the air from allergens. But, it must be true HEPA. Stay away from “HEPA style” “hospital-grade” or“HEPA like” filters. An air purifier for mold with a true HEPA filter can help allergies. All HEPA appliances had excellent efficiency measures. But the filters have to be replaced regularly. So pay attention to how difficult is it to change the filter. Dirty filters themselves can become a source for air contamination by allergens, particularly fungal spores. Remember that HEPA filters actually do not remove odors and only a few air purifiers have an enhanced HEPA filter sufficient to capture viruses, or a technology such as a sterilizer which uses heat to kill pathogens.

The Right Size of Air Purifiers 

The air purifier must constantly move the air in the room. To choose the right size device for your space. For the beginning, you must know the amount of the air is in the space.

The volume is calculated by multiplying:

Length of room x  width of room x ceiling height

The technical specifications will inform you about the quantity of the air the fan and motor can move. Find the amount of air moved by the motor. It will be called as “cfm” (cubic feet of air per minute).

To find out air exchanges, divide the volume of air in the room by the cfm of the machine. To determine the exchanges of the air per hour, divide 60 (the minutes in an hour) by the number of minutes for one exchange.

Will an Air Purifier Help Allergies?

Yes. But only if you have indoor environmental allergies, you get a purifier with a true HEPA filter and is the right size of the space.

In the long term, breathing in the dirty air can increase your risk of asthma, cause chronic lung problems and make it harder for your body to fight infection.

Recent studies of asthmatic children have shown that using an air purifier at home reduced symptoms and visits to the doctor. Aside from removing airborne particles, some air cleaners also work as odor-reducers.

But if you have dust mite allergies, air purifiers are not a silver bullet and you should buy dust mite covers for your bedding since dust mites tend to congregate in warm, moist environments.

An air purifier in the bedroom is highly recommended for people with allergies. Studies support multiple interventions, including air filtration, as methods to improve outcomes in the treatment of allergic respiratory diseases.

But it is important to remember, though, that an air purifier does not combat symptoms in the same way that medication does, so medication is a very important part of keeping symptoms at bay, especially if you are planning on venturing outdoors.
