Benefits of Using The Best Air Purifier for Allergies

There are many health benefits of air purifiers. Primarily, owning an air cleaner when you have allergy sensitivities is an easy way to improve your daily health. It’s also the most efficient and hands-free way to protect your home from allergen particle invaders.

Most people who don’t have an air cleaner rely on over-the-counter or prescription medications to help treat their allergies. While these solutions may help to treat the symptoms, the biggest problem is that you have to continue with these treatments in order to get relief. Additionally, the cost of medications continues to rise every year and this extra expense is a real burden on a lot of people.

By adding an air purifier to your home, you’ll have a device that’s dedicated to stripping the air of the harmful airborne particles that irritate your allergies so you can enjoy improved air quality. Once these contaminants are gone and kept at bay, you’ll find that you may not even need to take allergy medications anymore (or at a much lower dosage) saving you a costly monthly expense.

The short term daily exposure to allergens are irritating and can greatly affect your day to day life. Aside from these most common symptoms, long term exposure can also lead to excessive fatigue or regular headaches.

  • sneezing and a runny or stuffy nose
  • coughing and sore, scratchy throat
  • itchy or watery eyes
  • frequent headaches
  • excessive fatigue
  • dry, itchy skin and hives

If you’re a person who experiences allergy symptoms all year round, then a dedicated allergy air purifier is a great device to have inside your home. Air purifiers remove these pollutants before they have a chance to trigger your allergic rhinitis.

  • tree, grass and flower pollen
  • dust and dust mites
  • animal dander
  • mold spores
  • volatile organic compounds
  • cigarette smoke

What to Look for in The Best Air Purifier for Allergies

The first thing you’ll notice when shopping for an air purifier for allergies is that not all products are created the same. When it comes to figuring out what to look for in an air purifier and finding the best allergy air purifier that works for you, you really need to look for a few key features. Not doing so may cause you to buy an air cleaner that doesn’t work for your particular situation and won’t even give you much (if any) allergy relief.


A dedicated pre-filter air filter is a must-have because it offers two major benefits:

  • This air filter traps larger allergens like pollen and dust as well as pet hair, dirt, and debris.
  • This air filter prolongs the life of the True HEPA filter (mentioned next) so it can do its job more effectively at capturing microscopic allergens.

When looking at home air purifiers that target allergies specifically, you’ll want a device that has a separate, dedicated pre-filter that can be washed and reused.

The pre-filter is the first line of defense on air cleaners and prevents the other filters from getting clogged up too fast and lets them work to their highest ability. 

HEPA Filter

HEPA stands for “High Efficiency Particulate Air” and True HEPA filters are the best type you can get for cleaning the air.

  • It captures the tiniest allergy particles that cause your symptoms to flare, like dust, pollen, pet dander, bacteria, etc.
  • It traps and locks allergens inside and doesn’t allow them to be released back into the air.

First and foremost, no other type of air filter can capture particles as small as a True HEPA filter, making this feature crucial for anyone who suffers from allergies.

In fact, True HEPA air purifiers are designed to remove allergens as small as 0.3 microns. To help you visualize that size, a human hair is 2-3 microns which is more than 600 times larger than the smallest allergy particle.

Another powerful aspect of True HEPA filters is that once the particles are trapped, they then never get released back into the air. This means that after the air cleaner has had enough time to exchange all of the air within a room, it becomes allergen-free and then stays that way.

CADR Rating (Clean Air Delivery Rate)

An CADR air purifier rating is an independent standard for measuring a filter’s efficacy that’s assigned by the Association of Home Appliance Manufacturers (AHAM).

The CADR rating indicates air purifier effectiveness at removing smoke, pollen, and dust particles.

The higher the CADR number is for each type of pollutant, the faster the air cleaner can filter it.

CADR is broken down into three scores:

  • Smoke (10-450 CADR)
  • Dust (10-400 CADR)
  • Pollen (25-450 CADR)

If you’re comparing two or more air cleaners and wondering do air purifiers help with dust mites, then this CADR score will help to give you that answer.

ACH Rating (Air Changes Per Hour)

The ACH rating tells you how many times an air purifier can fully exchange the air within a certain size room. In other words, an air purifier that’s rated to handle 500 square feet and has an ACH rating of 5x means that the full volume of air in that size room can be exchanged five times every hour.

When you’re comparing the best air purifier units with the same room size coverage (square footage), the ACH number is important because it can quickly inform you as to which product does a more thorough job at cleaning the air.

Just remember that the ACH rating is related to the specified square footage (sq. ft.) coverage for the air cleaner. Therefore, if you place the air purifier in a room that’s smaller than the maximum size it can handle, the ACH rating goes up. If you place the unit in a larger room than it’s intended, then the ACH rating goes down.

Frequently Asked Questions About The Best Air Purifier for Allergies

Do air purifiers really work for allergies?

While many air cleaners claim to have the best air filter for allergies, studies indicate that the only types of filters that are efficient for this purpose are HEPA filters and PECO filters.

Acoordingly, a study found that using a HEPA filter reduces allergen concentration levels of dust and particulate matter in the air. Another study reported that allergy symptoms decreased significantly over a 4-week course of using a device with PECO technology.

Do air purifiers help with animal allergies?

By removing airborne pet dander and hair, purifiers can indeed keep pet allergen triggers out of the air. With an air purifier running, you can experience less pet dander allergies.

Is an air purifier or humidifier better for allergies?

Essentially, air purifiers remove airborne contaminants that trigger allergy symptoms. They do this by filtering the air and trapping the contaminants inside a set of air filters like a HEPA filter. A humidifier does not filter particles out of the air. Instead, this unit adds moisture to the air to increase the humidity.

Do you need more than one room air purifier?

The simple answer is at least one unit for the room you frequent most. Ideally though, you’ll want two air purifiers: one for the main living room and another for your bedroom. That way, you can have clean air in each of these rooms of the home at all times.

Another solution is to get a whole home air purifier. These units attach to the HVAC system and filter the incoming airflow that’s drawing into the system. In theory, this will purify all of the air inside the house but they can be expensive. 

Are air purifiers good for sinus problems?

Air purifiers are good for sinus problems because they remove allergens and other pollutants from the air in your home. For example, common triggers like dust, pollen, mold spores, pet dander, and tobacco smoke will clear. As the air purifier filters out these particles, your sinuses can feel better.

Are air purifiers recommended by allergists?

Air purifiers are recommended by allergists. Expert allergists recommend two types of filtration. The American College of Allergy, Asthma & Immunology points out that every “air filter has three key components, known as the ‘filter triangle’: its capacity, the amount of airflow it allows and its efficiency (how well it can trap particles). These three parts need to be balanced: A filter that blocks airflow will cause problems, as will a filter that doesn’t hold enough of the particulates you’re filtering.”
