Breathing clean, fresh air is a delight for everyone – but it’s an absolute necessity for allergy sufferers. If you have allergies to pollen, mold, smoke, dust, dander or any other inhaled particles, an air purifier can provide much-needed relief from these common triggers. These mighty machines can also make the air inside your home or office smell better, thanks to their ability to clear odors from a room.

There are many options when choosing an air purifier for allergies, but many machines feature a true HEPA filter. These specialized filters are able to clear out particles as small as 0.3 microns. To put this in perspective, our eyes can’t see anything smaller than 40 microns—so it’s safe to say that air purifiers with HEPA filters do a tremendous job of filtering out the majority of common allergy triggers.

However, some other quality options exist in air purifiers for allergies, including machines that use cold evaporation technology or the power of electrostatic energy to filter the air. These machines are good alternatives if you don’t want to frequently purchase replacement filters. Air purifiers for allergies are often grouped by the size of a room they can filter —with small desktop versions for office use and larger units capable of filtering 800 square foot or more.

You’ll also want to consider the CADR rate (which is the measure of how fast the purifier can refresh the air in the room), but know that the rate can change for contaminants such as smoke, pollen, or dander. Read on for the best air purifiers for allergies that can handle common triggers and are designed to give you fresher, cleaner air that will help you breathe easy.

Best Budget: Germ Guardian AC4100 Air Purifier

For air purifier on a budget, look to the compact GermGuardian AC4100. This tabletop HEPA purifier costs less than $100 and measures about 11 inches high. The small size of this model from GermGuardian makes it a good choice for small bedrooms or desks, but it would likely struggle to clean the air in larger spaces.

Packing these features into an air purifier for under $100 is a great value. Just be aware that reviews are mixed on whether the fan noise from this compact air purifier qualifies as noisy.

Best for Pets: Winix WAC9500 Ultimate Pet Air Cleaner

You love your pets, but your allergies may not. If you share your space with a furry friend and have allergies, you need an air purifier for pets like the Winix Ultimate Pet Air Cleaner. This air purifier features a pre-filter that is designed to capture pet hair, reducing the furballs you find under sofas and beds and that contribute to allergies.

To maintain the effectiveness of this pre-filter, simply remove and wash it on a routine basis.

People who purchase this air purifier for pet allergies are generally happy with its performance. But if you purchase it thinking that it will dramatically reduce the amount of fur on your furniture or eliminate your need to vacuum, you may be disappointed.

Make your home or office environment cleaner and more comfortable with an air purifier and humidifier in one like the Venta Air Washer. This device will purify the air and also maintain a comfortable level of humidity thanks to its two-gallon water reservoir.

The unit works to purify the air by removing particles up to the size of 0.3 microns. Without filters, this air purifier relies on a wet, rotating disk stack that catches incoming particles. Through the process of cold evaporation, only water evaporates into the air—leaving dust, dirt, dander, pollen and more on the inside of the machine.

It’s recommended that every 10 to 14 days you clean the disk stack and interior housing of the air purifier to keep it running efficiently. There are no filters to purchase for this air purifier, which is a major plus for most users. However, the company does advise the use of an additive that helps to keep mineral deposits from building up and allows the unit to function at peak efficiency by preventing the water from beading up on the disk stacks.

In real-world use, the Venta does a great job of maintaining optimal humidity levels and seems to help allergy sufferers, though it isn’t the most robust air purifier available. Those with heavy allergies may want to evaluate other models. If you don’t want to purchase air filters for your purifier and are also looking to add some humidity to your space, the Venta Single Room Humidifier Plus Air Purifier is an efficient, two-in-one device.

Best Electrostatic: Nectar Air Purifier

For an alternative means of controlling air quality, try an electrostatic air purifier for allergies. The Nectar Air Purifier uses electrostatic energy and a washable filter to catch and neutralize allergens. An ion air purifier like the Nectar uses a field of static electricity that zaps incoming contaminants like pollen, mold, germs, and more and then causes them to collect on the metallic filter where they can be cleaned and disposed of.

Many people find this to be more hygienic than having a filter that collects and stores allergens, bacteria, and more for several months before replacing it. It can also save you money in the long run, since you won’t need to purchase replacement filters. The Nectar Air Purifier’s stainless-steel filter will last with regular maintenance.

One thing to known about this air purifier for allergies is that it emits ozone at safe levels, which many people feel contributes to feelings of wellbeing and restfulness. Plus, ozone is useful for killing bacteria. For a filter-free way to combat airborne allergens, give the Nectar Air Purifier and its electrostatic energy technology a try.

While the lower levels of operation are found to be low decibel and peaceful as background noise, the turbo level is reported to be quite noisy. Still, if you don’t plan to operate the air purifier in turbo mode too often, you’ll find this unit to be quiet enough to fade into the background.

As for the performance of this Honeywell air purifier for allergies, people are very happy with its performance. It clears a considerable amount of pollens, dander, and debris from the air—to the point that people are equally delighted and disgusted when they change the filters.

For better air quality in a larger room or open-concept floor plan, choose an air purifier with higher capacity—like the Rabbit Air MinusA2.

People find the Rabbit Air MinusA2 to be a useful way to purify the air and relieve allergies. The customizable filters are also unique and make this a good air purifier for smoke as well.
