You should think of your house as a haven free of pollution and allergens. But here’s the thing: dust, mold, and chemicals that accumulate in enclosed spaces over time can make indoor air twice as polluted as outdoor air, even if you can’t tell by looking at it. During cleaning, keep windows and doors shut to prevent ‘polluted’ air from entering. Many allergens, such as pet dander and dust mite allergen, are easily spread through the air.

Allergies can cause coughing, headaches, fatigue, sneezing, wheezing, and congestion, which can make life difficult. Untreated allergies can lead to a variety of illnesses, including ear infections and sinus infections. This is why it is important to use the appropriate strategies to manage allergy symptoms. To control allergies, you’ll need to do more than just take medications. You’ll also need to take some preventative measures. Improving indoor air quality, which can be achieved with the aid of air purifiers for allergies, can play a big role in controlling allergy symptoms.

An air purifier is a device that purifies the air in your home by removing all impurities such as odors, smoke, dust, and pet dander.  some pollutants can be five times higher in indoor air than in outdoor air. Some models may even be able to target bad air that finds its way into your apartment or home, particularly if you live in a polluted or disaster-prone area.

You’re allergic to the skin flakes and allergens left behind by dogs, cats, and dust mites if you have a pet or dust mite allergy, for example. An air purifier aids in the removal of these particles from the atmosphere.  Air purifiers for allergies come with a HEPA filter that cleans all of the air in a room 3.5 times per hour may help with allergy symptoms. As a result, an air purifier does not alleviate all symptoms but rather increases the air quality to alleviate them. An air purifier for allergies will assist in ensuring that the air you breathe is cleaner. People with serious allergies should keep an eye on their indoor air quality. This is why choosing an air purifier for allergies gives you real-time feedback on the air quality in a room is a good idea. This air purifier for allergies buying guide is for you if you want to know what to look for in an air purifier or how to pick one.

Types Of Air Purifiers Filtration Technology

There are four basic types of air filtration technology that purifiers air:

  1. HEPA (High-Efficiency Particulate Air) Filtration: This air filtration method is widely regarded as the gold standard in air purification. It is the driving mechanism behind high-end machines, consisting of a dense paper filter that traps airborne contaminants.
  2. Ionic Filtration: This air cleaning technology works by releasing a cloud of charged ions into the air that clings to contaminants in the air. These impurities are forced to fall to the floor and other nearby surfaces as a result of this process.
  3. Carbon Filtration: This type of air filter employs a unique type of activated carbon with millions of tiny absorbent pores. The large surface area of these pres is ideal for trapping fumes, gases, and odors.
  4. Ultra Violet (UV) Light: Rather than moving contaminants via a physical filter, this device emits an invisible light that attacks them. The air purifier contains UV light, which is not released into the room.

The UV-C band of the ultraviolet spectrum is used by a UV light air purifier with this technology. This band is harmless to humans and has no harmful consequences.


Filter Type

The number and type of filters used in an air purifier for allergies determine its effectiveness to a large extent. HEPA filters, activated carbon filters (AC filters), anti-bacterial filters, and ionizers are among the most commonly used filters. All of these filters may not be present in an air purifier. However, the more the merrier, and it should have a HEPA filter.


There are a few labels on the packaging of the air purifiers for allergies that you can look for. To be efficient, air purifiers for allergies must run 24 hours a day, seven days a week, and you should factor in the cost of energy when shopping. You may also notice an AHAM Verified seal, which indicates that the model has been inspected by the Association of Home Appliance Manufacturers. Many air purifiers have undergone AHAM’s certification program, which includes clean air delivery rates (CADRs) and room size guidelines on the seal, despite the fact that it is voluntary.

CADR measures the volume of clean air produced by an air purifier at its highest speed setting in cubic feet per minute. A purifier with a CADR of 250 for dust particles, for example, reduces dust particle levels to the same concentration as adding 250 cubic feet of clean air every minute. The higher the CADR, the more quickly and effectively the air purifier works. The highest CADR is frequently achieved by portable air purifiers with HEPA filters. In our tests, a CADR of more than 240 is considered Excellent, 240 to 180 is considered Very Good, 179 to 120 is considered Good, 119 to 60 is considered Fair, and anything less than 60 is considered Poor.

Room Size

If an air purifier for allergies bears the AHAM Verified seal, you can rest assured that it can handle the recommended room size. However, the suppliers’ claims should be taken carefully.  There are a lot of air purifiers for allergies that aren’t suitable for the room sizes they claim to be suitable for.  Most models designed for large rooms (350 square feet and up) still work well at lower (quieter) speeds, which is convenient when watching TV or sleeping.


A fan is often included with air purifiers that use a HEPA or carbon filter to clean the air. This fan is responsible for drawing air into the unit and forcing it through these filters, which collect harmful particulates from the surrounding area. All fans, as you may know, make noise. The lower the noise level, the slower the fan speed, and the higher the fan speed, the louder it sounds. Most air purifiers have at least two (low and high) speeds, and some have up to five (low, medium, high, turbo, and automatic).

You should not only consider how well an air purifier performs, but also how well you will be able to live with it. These machines should be kept running at all times, so they should be silent. (A noise level of around 50 decibels is approximately equivalent to that of a refrigerator.)

Before you buy, you might be able to find out how many decibels a model runs at on its packaging or website listing. If the air purifier for allergies you purchase is too small to handle the size of the room it will be placed in, it will run at higher speeds than usual to compensate. This also means that it will always be turned up to its maximum volume.

Maintenance Costs

When air purifiers are properly maintained, they perform at their best. Before you buy an air-purifying device for your home, make sure you understand how much it will cost to keep it running smoothly. Air purifiers’ HEPA or carbon filters would need to be checked on a regular basis. These filters trap particles inside them and eventually become clogged, rendering them unable to clean the air.

The amount of use and the air quality around the unit will determine how long the filter lasts. If you’re considering purchasing an air purifier with a HEPA or carbon filter, find out how often the manufacturer recommends replacing it and how much replacement filters cost. The lifespan of a filter can range from three months to a year. The price of a filter can range from $15 to $50.

You won’t have to worry about maintenance costs if you buy an ionic air cleaner. This is due to the lack of a degradable filter in these machines. A type of electrostatic collection filter is included in some ionizers to collect harmful particles from the air, but this filter is washable and reusable. Ionic air purifiers are the cheapest to purchase and maintain.

Power Consumption

Different types of air purifiers for allergies, like all appliances, need a different amount of energy to operate. Because air purifiers must run constantly, you should think about your utility bill before purchasing one. The majority of air purifiers need between 50 and 200 watts to operate properly. Select the choice that uses the least amount of energy.


The efficiency of air purifiers for allergies varies depending on the model and the number of airborne particles they can remove from the air. In addition, when evaluating its performance, make sure to take into account the square footage as well as the effectiveness.


If you intend to buy an air purifier for allergies for long-term use, it’s a good idea to check the manufacturer’s warranty to avoid problems later. In the long run, this may help to avoid potential issues. Before purchasing a product, determine whether or not the air purifier’s parts, such as the engine, fan, or electrical components, are covered by the manufacturer’s warranty just in case they break down.

You don’t want to keep replacing an air purifier because it’s a long-term investment. You don’t want to buy a product that breaks down and then discovers that the warranty didn’t cover the product’s critical mechanisms or that it didn’t last a long time.

After-Sales Service

Before purchasing an air purifier for allergies, inquire about the manufacturer’s pre-and post-demonstration or installation services in your area. To prevent any inconvenience, ask the manufacturer about the maximum time and make sure the manufacturer offers prompt after-sales services if there is a problem with the purifier.

Available Prices

Air purifiers for allergies come at a different price according to their features and the service provided. You can find the low-cost ones under $200 and the medium-priced ones that range between $200-$500 and the high-cost, best-quality ones that would cost you above $500. But we would also recommend you to look after other factors while buying one.
