Best air purifier for allergic rhinitis

Hayfever is characterized by flu-like symptoms such as itchy eyes, runny nose, sinus pressure, congestion, and sneezing. People who contact this have to see a doctor frequently for treatment. However, the good news is that it is caused by allergic responses to outdoor or indoor allergens such as pollen or dust mites, which can be removed from the air with an air purifier. Running the best air purifier for hayfever eliminates these allergens in the air, leaving your body with nothing to trigger such reaction.

Hay fever, also known as allergic rhinitis, is caused by allergies, and if you can deal with the allergen causing such reactions, then you would be free from its symptoms. To help you in dealing with such allergens, we have put together a review, which includes the best hayfever air purifier for you. This unit contains the best air filter for hayfever allergens.

IQAir 1CC UB0 HGB is a medical-grade air purifier that contains a filter that is 100x more effective than a traditional Hepa filter. It filters allergens down to 0.003microns; therefore, no allergen would get away from it.

How to choose the best air purifier for hayfever

There are things you must put into consideration before buying an air purifier for an illness. Below are features we used in reviewing and selecting the best air purifier for hayfever in the market.

  • Filtration method (HEPA and carbon filters):

The two compulsory filters that an air purifier must have in dealing with allergens are the true HEPA and activated carbon filter. The HEPA filter isn’t limited to only a true HEPA model but can be better (like the medical-grade type seen in IQAir). Although other filtration stages can still exist to further supplement, the air purifier you purchase must have these two primary filters.

  • Noise level:

Preventing hayfever means that you would probably have to purify the whole house, which includes your bedroom. Noisy units create discomfort at night and should be avoided as much as possible. The air purifier for allergic rhinitis should be quiet to some extent.

  • Room coverage and capacity:

Depending on the size of your home or a specific room, the unit purchased should be able to clean the air at least 3-5 times per hour. This involves a high air suction level. Not only should it only have a high area coverage in square feet, but it should also have a good fan that moves air, hence a good clean air delivery rate.

  • Other features:

These include a timer, auto mode, remote control, Wi-Fi, and artificial intelligence-enabled. The more of these features it has, the better the user experience it would provide. It would also be easier to use. A timer allows you to select the units precise runtime, while the auto mode runs the unit according to air quality demand, and a remote control/ Wi-Fi/ artificial intelligence-enabled only helps you operate the unit easier.

IQAir brand is in the business of making high-quality air purifiers. Their products are mostly medical grade and come with modern features that give an awesome user experience. This particular product is the best air purifier for jay fever sufferers.

Medical grade filtration with triple seal technology

The standout quality in this air purifier is its medical-grade design. This unit is built with a special medical grade Hepa filter, which is 100x more powerful than conventional true HEPA filters. They capture all household allergens like dust mite and pollen and even go further in trapping ultrafine particles. Ultrafine particles (0.003) are smaller than conventional pollutants (0.3) in size; therefore, they cannot be captured by most air purifiers out there.

Its filtration system also consists of an activated carbon filter. The unit contains 4 GC MultiGas media, which are made of the highest-grade activated carbon from bituminous coal. Other types of carbon filters are made from lower grade coconut shell. It does not make use of zeolite and contains alumina pellets impregnated with potassium permanganate for removing formaldehyde from the air. With this unit, gaseous, physical, and ultrafine particles would all be trapped.

Its multigas cartridges and filters are air sealed with a triple-sealed technology; therefore, air flowing through only passes through the filters and nowhere else. Impressively, it does this while offering very low airflow restriction.


Asides a very impressive air filtration system, this unit also high airflow capacity. This is possible through a maintenance-free fan that delivers up to 300CFM at only 27 watts at the lowest speed. Clean air is expelled into the atmosphere in a 320-degree manner due to the unit’s design. It is suitable for serving large sized rooms of up to 1,125sqft, which makes it very suitable for the whole house or single room usage.

Remote control and timer

Noise level and filter life

It operates very quietly and can be used in bedrooms without constituting a nuisance during your sleep time. Its filters last very long; 12 months for the pre-filter, 2.5 years for the gas/ odor filter, and 2.5 years for post filters sleeves. A filter life indicator starts to glow, signaling you when it’s time to change the filter.

PECO technology

This unit’s standout feature is its use of PECO technology. With the photochemical oxidation nanotechnology, the air purifier does not trap but destroys viruses, volatile organic compounds, allergens, mold, and bacteria.

The PECO is a light filter, which activates the nanoparticle-coated filter that breaks down pollutants at the molecular level. This technology places it in the best air purifier for allergic rhinitis class.

Another advantage of PECO technology is that it does not emit ozone or any other harmful byproduct into the air. This unit is not without a standard pre-filter too.

The pre-filter helps to trap large sized parties, preventing them from getting into the unit. The filter, however, has a short lifespan of only three months, while the PECO filter lasts for six months.


Although it cannot quite match the over 1000sqft capacity of IQAir, this unit is able to clean the air in rooms up to 600sqft, with very good accuracy. Its round body design allows it to take in air in a 360degree manner, cycling air in the room in a much shorter time than one direction devices.

There are three fan speeds that you can choose from, depending on the level of contamination in your home.

Easy to use

With a touch display screen, and Wi-Fi enabled smartphone control, this unit couldn’t be easier to use. The touch display allows you to easily interact with the unit, and it’s located at the top side for more comfort.

Its design accommodates Wi-Fi control, which allows you to easily vary settings like fan speed and check the units filter life. The app is, however, limited because that’s just about all you can do with it. It is a good addition, however.

Good design

With a clean and smooth finish, the anodized aluminum material body looks appealing to the eyes. It is well rounded and has the overall appearance of a furniture piece.

It also has a handle, which is laced with premium leather that should make it easier to lift off the floor. The unit is, however, very heavy and is not so easy to carry. The presence of a handle doesn’t make up for this.


  • It makes use of electrochemical oxidation nanotechnology (PECO Filter) to destroy viruses, allergens, VOCs, mold, and bacteria. This technology also destroys ozone.
  • Designed for large-sized rooms of up to 600sqft with 360-degree air intake
  • With a touch screen display and Wi-Fi smartphone control, it is very easy to use
  • Simple and good looking design with handle for carrying grip


  • The unit is very heavy

Ultrahepa and carbon filter for better filtration

This air doctor product once again beings a filter that is more efficient than the conventional HEPA filters seen in air purifiers. The ultrahepa filter built into this unit is 100x more effective than HEPA air filters, according to its manufacturer. This filter cleans the air with a 99.95% accuracy and traps particles as small as 0.003microns in size.

The filtration system of this unit is also enhanced by two extra filters. The first is a washable pre-filter that captures larger particles to enhance the life of other filters, as well as a dual-action carbon/ gas trap filter. This gas filter removes molecules of ozone, gases, and volatile organic compounds in the air.

Automatic mode with timer

Built into the humidifier is a sensor that keeps track of air quality and works to match that quality accordingly. The poorer the air quality (more contaminations), the faster the fan would run, and vice versa, this way, you can allow the unit function without having to keep getting involved.

Its automatic mode also comes with a timer, which further helps to manage the air purifiers work schedule. With a timer, it runs for that particular set time and turns off after.

Although it works most of the time, the auto mode is not reliable due to poor sensor qualities that fail to pick up some contaminants in the air.


The fan has a good capacity, providing enough for the unit to have a clean air delivery rate of 373. It is built for a large-sized room and can cycle the air three times in a 900sqf rating. All these qualities put the air purifier as a high capacity product, and we are confident that it would do your large room a lot of good.

Energy efficient

Probably the most underrated feature of this unit, it is built to be energy efficient, therefor it adds very little to energy bills come month-end.

An overall look at this air purifier, however, states that it comes at a poor quality for the price. It also has quite a few cons, like being loud and having very expensive and scarce filters.

  • Filters are very expensive to replace and hard to find
  • Poor air quality sensor makes the auto mode noneffective
  • It generates loud noise when operating, even in the lowest setting.
  • It produces a chemical smell when running
  • Comes at a poor quality for the price

Multifunctional product

This unit is multifunctional in the sense that it has an ordinary fan mode attached coupled with it being an air purifier. You either operate it to work as an air purifier, while the fan dispenses purified air to help circulate it properly around the room, or simply run it in the backward mode which purifies the air without running the fan.

On the other hand, you can also choose to run the fan alone. This mode is called backward airflow, where the unit purifiers air without cooling you.

Effective filtration

It contains two sealed HEPA filters that capture 99.97% of allergens as small as 0.3 microns. This makes it ideal for allergens, dust, pet dander, mold, and pollen. The HEPA filters are also sealed with activated carbon filters, whose job is to remove gaseous contaminations.

The body structure of this unit allows you to oscillate at different angles for directing the air to exactly where you want. You can rotate it up to 350 degrees. Its round shape also helps it drawn air in a similar manner from different angles of the room.

Automatic mode with air quality sensor

This mode simply allows the unit to run independently while giving the user feedback on air quality. It has a digital display at the front, which displays the air quality measured by highly sensitive sensors. It also indicates that it is running on auto mode when set to the mode.

When running in this mode, the unit measures pollution in the air and varies its fan speed to compensate accordingly.

Alexa enabled and remote control

This is a very modern unit, and the Alexa feature proves just that. It is compatible with an Alexa AI, which allows you to use voice command in requesting parameters such as air quality, turn on auto mode, and turn on or off the unit. Air purifiers do not get more modern than this currently. It also supports remote control and comes with one too. This allows you to control the unit from a distance.


  • Multifunctional air purifier and fan with air multiplier technology for even distribution
  • Uses sealed HEPA and carbon activated filters for effective air cleaning of 99.97% of pollutants down to 0.3 microns

5) Germ Guardian True HEPA Filter Air Purifier with UV Light Sanitizer 

Best affordable HEPA air purifier
Check the price of this product

Germ guardian manufacturers are known for producing budget air purifiers but are also pretty good for their price and quality. This unit is the best cheap air purifier for hayfever on our review list, and rightfully so because it offers very good performance when tested in a recommended room size.

4-stage air filtration

The 4-stage air filtration consists of a pre-filter, HEPA filter, carbon activated filter, and UV light (it can be turned on or off at will). The HEPA filter meets the standard, and traps 99.97% of harmful pollutants in the air, down to 0.3 microns.

Its activated carbon filter helps reduce unwanted odors from pets, and other domestic odor sources like cooking. Lastly, the pre-filter traps large particle contaminants in the air, giving the HEPA and carbon filter a longer life as a result.

These filters last between 6 to 8 months before requiring a change, and according to the manufacturer, replace with either a guardian filter c (flt5000) or a four-pack of guardian carbon filters (flt28cb4).

Timer with UV light

It also has a built-in programmable timer. This timer spans from 1 to 8 hours, allowing you to choose any amount in that range, and the device works with it. After the time is expended, it goes off.

For an extra layer of filtration, you can decide to turn on the UV light, which helps attack contaminations at a micro-level. The UV compartment of this unit is very small, and not all the air flowing through can get properly filtered as a result. Do not put very high hopes on its UV filtering capacity.


The capacity this product is unsurprisingly a letdown considering its price and features. It is built to serve rooms of up to 167sqft in size, which really limits its abilities. The upside, however, is that it has very good clean air delivery rates of 114 for dust, 127 for pollen, and 108 for a smoke when used in the recommended area.

It is noisy at higher speeds, and not effective on lower ones. The lights are also very bright and cannot be turned off.


  • 4-stage air purification consisting of a pre-filter, HEPA filter, and activated charcoal filter traps 99.97% of pollutants down to 0.3microns.
  • Programmable timer and an optional UV light
  • CADR rating of 114 for dust, 127 for pollen, and 108 for a smoke.
