We recommended having extra filters to make the replacement process easier.

Taking off the plastic from the elements and the carbon filter ensures that the filters work properly at removing contaminated air within your living space.

A common question that consumers ask is “what is the best air purifier for allergies?”

And the correct answer is “It depends.” There is a multitude of allergies out there, and you need to know which purifier can do the most for you.


Here are a few common household allergies that are treated through the use of air purifiers:

  • Dust Mites
  • Mold
  • Cockroaches
  • Pollen
  • Cigarettes
  • Dust Mites

These are the most common allergens found in your home. Dust mites are microscopic insects that trigger asthmatic reactions and feed on human skin flakes. Their main habitats are in areas of 40% humidity and up to 75 degrees Fahrenheit.

You’ll want to have an air purifier that comes with a HEPA filter to deal with dust mites. Dust mites are within the 0.3 micron range because they are hard to see in the human eye. Through the use of HEPA filters, dust mites are easily captured and removed due to their powerful filtration mechanisms.


Black Mold is a common threat amongst American Household. It tends to grow in dark environments such as the basement in your house. You need to have a purifier that has an ionizer feature to combat this harmful air pollutant.


Mold tends to grow on the walls in your house. This is a dangerous situation especially if you have drywalls in your home. Your drywalls will have to be replaced with a new set which can cause thousands of dollars. Because of this, you need something that can eliminate mold before it becomes a larger issue.


This pest is an allergen that can trigger people who have asthma. Cockroaches are in issue in inner city regions and Southern regions of the United States. If your house or room has a moisture level that is above 50%, chances are you might come in contact with them.

Buying an air purifier is one method to prevent cockroaches from reaching your home. Keeping your house free from air pollutants allows your house to remain clean and safe from cockroaches. Invest in an air purifier if you believe that your house is infested with roaches.


Most people don’t think that pollen can plague their households. This is a common myth because you can attract pollen on your shoes in your clothes during summer weather.

In fact, your pets can be a catalyst for pollen as well. Which can lead to people to assume that they’re allergic to the pets when they are allergic to the pollen that’s attached to their fur. Because of this, you should get an air purifier to prevent this secret allergen from infesting your home.



Cigarettes are not a traditional allergen by any means. However, they can trigger allergic reactions and can be dangerous for people who have asthma. Second-hand smoke is the leading cause of pain for asthmatics and should be avoided as much as possible.

The smoke from cigarettes emits gasses that can irritate the bronchial passages in the body. For asthmatics, this is very dangerous because their bronchial passages are already inflamed. Also, smoke can increase the severity of asthma attacks which can lead permanent damage to your overall health.

You’ll want an air purifier with a filter that can capture the smoke from cigarettes. It should be robust enough to remove at least 0.3 microns and other toxic gasses that can pollute your living space.


To understand the HEPA standard, you must also know the difference between HEPA and True HEPA filters. The main difference between them is the accuracy of their particle collection and the size of the particles that they can collect.


The HEPA standard is a procedure that is used to measure the efficiency of the filter. To pass the test, the filter must be able to remove up to 99.7% of the allergen particles that are found in the air. Also, it must be able to capture particles that are up to 0.3 microns in size that pass through the filter. If it passes, then it’s considered a True HEPA filter.

If the HEPA filter passes the standard examination, then it's considered a True HEPA filter. This is great because it means that it’s going to be effective at cleaning and clearing up the air. However, regular HEPA filters collect up to 99% of the particles and are used to capture them up to 2 microns.

Most of these particles are too small for the human eye to see. That doesn’t make them any less dangerous. If inhaled, these particles can have some serious long-term effects on your respiratory and general health.

You’ll want to get a filter that passes the HEPA Standard. If it does, chances are you’ll have something that can quickly regulate the airflow within your living space. These filters are effective and should be taken into consideration when looking for an air purifier.


The Honeywell HEPA Allergen Remover is the winner. Unlike other products on this list, this one offers the most versatility. It comes with three element filters and a pre-filter which all work together to remove harmful air particles in your house. Consumers find this purifier one of the best purifier for dust mites as it captures and removes them from the atmosphere.

Ultimately, air purifiers are starting to become more demanded in today’s market. As technology improves, more efficient purifiers are manufactured. This gives the consumer an advantage because it makes it easier for them to receive a cleaner and healthier air space. Shortly, expect to see high-quality purifiers at an affordable price for the average consumer.
