1. Rabbit Air MinusA2 Air Purifier for Allergies

How would you like an air purifier with the most advanced air cleaning technology that can eliminate more than just allergens from your home?

Would you love to get rid of dust, pollen, bacteria, mold spores, pet dander, smoke, bacteria, and any other allergen that can impact your health?

If so, then this is going to be your top air purifier choice for allergies.

It’s one of the only products that’s certified by the Asthma & Allergy Foundation of America, which independently tests products to ensure that they meet the demands for people with allergies and asthma.

What makes this unit so powerful is the fact that it uses six-stages of air purification and deodorization technology.

In fact, it’s the leader in the industry for cleaning the most pollutants from indoor air.

With this air purifier you’ll get:

  1. Pre-filter
  2. Medium Filter
  3. BioGS HEPA Filter, which is a longer-lasting True HEPA filter
  4. Customized Filter

  • Odor Remover Filter: Reduces odors from pets, cigarettes and cigars, cooking, and mildew

Another feature you’ll enjoy is that this air purifier can be wall-mounted or stand alone as a floor unit. No other model available today gives you this type of luxury.

Also, the front panel comes in two color choices and multiple designs, and a Wi-Fi enabled version lets you control everything from your iOS or Android device.

All-in-all, we consider this to be the best air purifier for allergies because it has the most customizations and it cleans the air in a large room between 700 to 815 square feet.

Perhaps it’s the right unit for you too.

2. Honeywell HPA250 True HEPA Allergen Remover

If you were to ask an allergist or immunologist what they recommend as the best air purifier for allergies, 9 times out of 10 he or she would recommend a Honeywell product.

And the one device that continues to outrank all others for allergies is this Honeywell HPA250.

What makes this product so special is that it meets strict guidelines set by the Association of Home Appliance Manufacturers (AHAM) and delivers a Clean Air Delivery Rate (CADR) performance rating of 200, which is fantastic.

This air purifier achieves that high rating by using an odor-reducing pre-filter and True HEPA filter to trap all types and sizes of allergens.

This top rated HEPA air purifier for allergies also has an Air Changes Per Hour (ACH) rating of 5X, which is one of the highest efficiency ratings you’ll find.

This means it can clean the air five times per hour in a room up to 310 square feet (around a 20′ x 15′ size room).

That’s exactly what you want out of the best allergy air purifier for large rooms in your home.

Plus, it has Bluetooth connectivity. This gives you wireless control through your smartphone to a 24-hour timer, custom air cleaning schedules, fan speed settings, filter reminders, and more.

At an extremely affordable price (compared to most other options) this is the best allergen air purifier you can get.

3. Honeywell HPA100 True HEPA Allergen Remover

Consider the Honeywell HPA100 to be the little brother to our #2 recommendation.

It’s similar to the HPA250 listed above but is made for someone who doesn’t need to purify a large space (i.e. bedroom, home office, or spare room).

It boasts a 100 CADR rating and can handle a room size up to 155 square feet (roughly a 10′ x 15′ space).

While it lacks the Bluetooth smart controls, it’s still a great buy for anyone who wants the best HEPA filter air purifier without spending a lot of money.

4. Alen BreatheSmart True HEPA Air Purifier for Allergies

Now if you liked our #1 review, but want an allergy air purifier that can handle an even larger space (i.e. a full basement or large open area upstairs), then you might want to consider this unit here.

It has some of the largest coverage available and can handle huge spaces up to 1,100 square feet (around a 30′ x 36′ size room).

In addition to offering a pre-filter for capturing the largest allergens and a True HEPA filter for trapping the finest particles down to 0.3 microns, you also get the pleasure of customizing the HEPA filter to further meet your needs.

You have the choice between:

  • HEPA-Pure which is made specifically for allergies.
  • HEPA-Silver which has additional layers of protection for asthma.
  • HEPA-FreshPlus which helps to cut down on smoke and airborne chemicals.
  • HEPA-OdorCell which has molecular conversion powder to reduce pet and baby odors.

Additionally, you can customize the front panel to suit your individual taste and styles—choose between 14 colors and designs including white, blue, brushed bronze, brushed stainless, black, rosewood, natural maple, and more.

Similar to our #1 review of the HPA300 listed above, this is another one of the best air purifiers with HEPA filter because is that it has a 300 CADR rating, which is exactly what an allergy sufferer needs.

As for ACH rating, this model exchanges the air 2X per hour in a room up to 1,100 square feet. That’s less efficient than the HPA300, but if you choose to place it in a room that’s smaller than 1,100 sq. ft., then that air exchange rate will go up.

Overall, this is a great air purifier for allergy sufferers who want a customizable HEPA filter, color options, and need to cover large areas in the home.

IQAir HealthPro Plus Air Purifier5. IQAir HealthPro Plus Allergy Air Purifier

If you want an extremely powerful air purifier that strips the most microscopic allergens out of the air, this model will far surpass your needs.

What makes it so outstanding is that it has a Medical-Grade HyperHEPA filter that captures particles that are 100X smaller than a standard True HEPA filter—0.003 microns to be exact.

It has a special V5-Cell Odor and Gas filter that extracts harmful chemicals and gases from the air that also trigger allergies and do harm to your health.

For serious allergy suffers, this machine will work wonders for the air around you at home.

It exchanges the full volume of air 2X every hour up to 1,125 square feet (roughly a 38′ x 30′ size room).

That makes this air purifier good for even the largest areas of your home or apartment.

As for the CADR rating, IQAir doesn’t measure their air purifiers with that number, but rather uses CCM (Cumulate Clean Mass), and it’s one of the only products whose particulate CCM rating is tested above 1 million mg.

Without going into complicated details, this makes the HealthPro Plus the best-of-the-best for long-term performance.

And finally, it’s hard to find anyone who doesn’t like this air purifier once they try it—the reviews speak for themselves.

It packs a lot of power with extremely high-quality filters and is known to provide amazing relief for allergy sufferers.

6. AeraMax 100 True HEPA Air Purifier

Similar to our #1 review above, this air purifier is also certified by the Asthma & Allergy Foundation of America, but it comes at a much lower price point and is a good allergy air purifier for personal use and small rooms.

With this air purifier, you’ll get 100 to 200 square feet of coverage, making it ideal for small bedrooms, studio apartments, or travel purposes.

The CADR rating is 70 and the ACH (Air Changes Per Hour) is 3X, so it’s very efficient at cleaning the air.

This unit includes the essential True HEPA filter for removing pollen, ragweed, dust, mold spores, and other common allergens as well as an Antimicrobial Treatment to prevent the growth of odor-causing bacteria.

A unique feature of this air purifier is the “PlasmaTrue” technology.

This technology boosts performance by emitting electrically charged ions into the air that causes allergens to cluster together so they can be trapped more easily by the internal filters.

If you’re looking for one of the best air purifiers for allergies that’s inexpensive and has a certification to back it up, then this is a great choice.

7. Molekule Allergy Air Purifier

Our final recommendation for an allergy air purifier is this newer unit by Molekule.

Molekule is breaking barriers in air purification technology by using a proprietary air filtration technology that actually destroys—not traps—airborne pollutants at a molecular level.

If you want a unit that can eliminate all traces of airborne allergens and other harmful contaminants from your indoor air, then this air purifier will far exceed your expectations.

It’s unlike any other air purifier reviewed on this list because it uses advanced PECO filtration technology:

  • PECO technology destroys allergens, mold, bacteria, and viruses at their core so you have the cleanest, healthiest air to breathe.
  • PECO filtering can eliminate pollutants that are 1,000 times smaller than standard filters must meet to qualify as HEPA.

Additionally, this air purifier is designed for large rooms up to 600 square feet, so it can handle most anyone’s needs for a bedroom or living room.

  • A smaller Molekule Air Mini handles up to 250 sq. ft. if you don’t have a large room to cover.

You can control this air purifier in two ways:

  • With the touch screen display on the top of the unit.
  • With Wi-Fi control by syncing it up with your iPhone or Android device.

There’s nothing else like this air purifier on the market today.

So if you want total particle elimination, then this is the right air purifier for you.

Allergy Air Purifier Buying Guide

Now that you’ve seen a list of the best air purifiers for allergies, you may want some additional help on how to select the model that’s right for you.

If so, this section can help.

By reading the information below, you’ll understand why the air purifiers reviewed above are the best HEPA air purifiers for allergies you can get.

Aside from those devices topping the charts with customer reviews, they also include the most important features necessary to help with allergy symptoms.

What to Look for in the Best Allergy Air Purifier

Best Allergy Air PurifierOne thing you’ll quickly learn when shopping for an air purifier for allergies is that not all products are created the same.

In fact, there are many different types of technologies that air purifiers use to clean the air.

When it comes to finding the best allergy air purifier that works, 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 give you much (if any) allergy relief.

To prevent that from happening, you’ll want to look for the following things.

The Top Air Purifiers for Allergies Include:


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

  • It traps larger allergens from pollen and dust.
  • It 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 air purifiers that target allergies specifically, you’ll want a device that has a separate, dedicated pre-filter that can be washed and reused.

That way you can keep your cost of ownership down by protecting the True HEPA filter from larger particles.

The pre-filter is the first line of defense on air purifiers and prevents the True HEPA filter from getting clogged up too fast.

This allows the True HEPA filter to work best at capturing the ultra-fine particles that irritate your allergies.

True HEPA Filter

A True HEPA filter is also essential for these two reasons:

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

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 can 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 this a True HEPA filter is that once the particles are trapped, they never get released back into the air.

This means that after the air purifier has had enough time to exchange all of the air within a room, it becomes allergen-free and stays that way.

So, the longer the air purifier runs in your home, the less you’ll experience allergy-related symptoms.

More About CADR and ACH Ratings

In our reviews above, we mentioned two important concepts for each product:

  • Clean Air Delivery Rate (CADR)
  • Air Changes Per Hour (ACH)

The reason we pointed those ratings out to you is that they’re important for anyone who suffers from allergies.

CADR Explained

The CADR 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 how well an air purifier is at removing smoke, pollen, and dust particles.

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

CADR is broken down into three scores:

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

ACH Explained

The ACH rating tells you how many times an air purifier can fully exchange the air within a certain size room.

For example, 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 home air purifiers 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.

Clearly, a 3x ACH is worse than a 5x ACH and a 6x ACH is better than the 5X ACH.

Just remember that the ACH rating is related to the specified square footage (sq. ft.) coverage for the air purifier.

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, the ACH rating goes down.

Benefits of Owning the Best Air Purifier for Allergies

Air Purifier for AllergiesOwning an air purifier 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 purifier tend to 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.

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.

This is especially true for those of you who suffer from allergic rhinitis or hay fever.

One of the biggest culprits for triggering symptoms related to these issues is pollen.

Therefore, the less pollen that’s in the air around you, the less you’ll experience sneezing and coughing, suffering from a runny or stuffy nose, and dealing with itching, watering eyes.

The same thing is true for people who suffer from dust allergies.

The best HEPA air purifier for allergies will suck in and collect the dust particles that float around inside your home.

Once this dust is trapped, it can’t re-enter the room or get into your eyes, throat, or lungs.

Another positive side effect of using an air purifier is that you’ll be getting rid of other harmful particulates that you may not even know are causing your health and respiratory issues.

This includes bacteria, viruses, mold, volatile organic compounds, etc.

As we mentioned at the beginning of this guide, an air purifier with a True HEPA filter is the best type of device you can get because it captures the smallest sized particles possible.

Using such a machine inside your home will create a clean air zone that’s free of both toxins and allergens.

Most people start feeling a better overall sense of health after just a few days of use and can really notice a difference when they’re inside another person’s home or buildings where an air purifier is not present.

Hopefully, this information has been informative to you and has helped you understand how valuable an air purifier can be for your allergies.

The best air purifier for allergies we recommended above are currently your top options when it comes to finding an air purifier that’s targeted for allergy relief.

Suffering from allergies doesn’t have to be an uphill battle.

Fortunately, there’s now a way in which you can control them better while at home—using the best allergy air purifier you can find.

Once you come into contact with an allergen, you’ll immediately experience one or more of the above symptoms.

However, some of those issues require long-term exposure to allergens such as excessive fatigue and headaches.

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.

Removing as many allergen particles as possible from indoor air can give you the much-needed relief you’re after.

  • tree pollen
  • flower pollen
  • grass pollen
  • dust
  • dust mites
