If you have an allergy or you have a family member who has one, you know living with this condition can be difficult especially if you have an active allergy. There are many ways to prevent having allergy attacks.

You can always rely on medicines to cure allergies. However, prevention is always better than cure. You just can’t rely on medicines to keep your allergies at bay. Therefore to prevent getting an attack, you must keep your environment free of allergens. One of the tools that can help you maintain an allergen-free home, is by getting an air purifier.

In this section, we’re sharing the list of the Best Air Purifiers for Allergies 2021. But first, you must know the factors to consider when buying this kind of product.

Factors to Consider When Buying a Humidifier for Allergies


Air purifiers that can fight against allergens and other allergy-triggering particles can be a hefty investment. But if this product can help you achieve a better and more comfortable life, we can assure it’s a worthy purchase. To make sure you’re getting the right air purifier for your needs, here are a few components to start with when buying this kind of product.

Room Size

Not all air purifiers are the same when it comes to their area of coverage. When buying this device, you must align your room size to the coverage of the air purifier. One rule of the thumb is to buy a machine that can cover a larger space than where you plan to place it. You can find air purifiers that can cover about 150 square meters to more than 300 square meters.

The first step when shopping for an air purifier is to identify the size of the room where you will place the product. Then opt for an air purifier that can cover a larger space than the room. This way, not will only that you can be sure it can cover the space where you are planning to place it, but it also, you can still use it if ever you move it to a larger room.


Looking for certification is one of the most important factors to consider when getting an air purifier. If you won’t see any certification that attests to the product’s ability to fight against allergens, it would be waste if you buy the wrong product. Typically, manufacturers always highlight this feature in the product description or when they market the air purifier. If ever you’re not sure about it you can always ask the seller if the product has certifications.

You may find a few kinds of certifications when it comes to air purifiers. Tags like CARB Certified, FCC Certified, ETL Listed, and Energy Star Certified are the usual accreditations that you may find when you shop for an air purifier. If you want to be sure if the product you’re getting has been certified effective against allergy, you can always confirm it with the seller. 



The level of noise that the air purifier produces is also an important feature to check during your purchase. Knowing that you will use this product regularly if not the whole day, you wouldn’t want a loud machine that can disturb you or the people inside your home. You will know the level of noise of an air purifier when you see a number in decibels. If you find an air purifier that produces noise at 60 decibels or more, there is a chance that this product is louder than most models in the market. 


Filters are also a crucial feature to check when getting an air purifier. Filters are responsible for air purifier’s ability to clean the air. You may find models equipped with HEPA filters as these filters are most commonly used for air purifiers for allergies. You may also want to know if the filters are placeable and how much it would cost for replacements.

Usually, the filters equipped in the air purifiers must be replaced more or less every year. These filters may cost a few bucks. Meaning, if you are budget conscious, you should take into consideration. On the other hand, there are models equipped with washable filters. You may want to prefer air purifiers with filters that you can wash. It can help you save money from not buying or replacing these parts regularly.


If you are budget conscious, clearly the cost of the air purifier you’re getting must be taken into consideration. To make sure you’re making the most of your purchase, some factors will help you get the best product for you. Features like durability, warranty, efficiency, and versatility are some of the components you may want to include when weighing out the cost and perks of the product you’re getting. 

It’s not always the case that the cheaper the product, the better. You can make the most of your money when you get a durable and efficient product that you can purchase at a reasonable price.

Size and Weight


The size and weight of the air purifier may also matter during your purchase especially if you live in a small space. If you have limited space, you would want to opt for compact air purifiers. Also, these machines are commonly moved from one room to another. Therefore you must take into consideration the weight of the product you’re getting.

The lighter the air purifier the easier it is to carry from one place to another. Some consumers also include the product’s design on their purchase. Good thing, there are lots of varieties when it comes to the design of these models. You can now choose the air purifier which you find the most appealing.

Temperature Range


Some models have a particular operating temperature range. This means the air purifier works best within a range of temperatures. You may also want to consider this factor during your purchase as it determines the product’s versatility. Choose an air purifier that can work within a wide range of temperatures. This way, you can be sure you’re getting the most of what you paid for.
