How to choose the right Air Filter for you?

When it comes to buying an air purifier, it is important to take into account which machine will address our specific air quality issues. Air cleaners have plenty of technical features which need to be studied before making a purchase. But even before that you must examine why you want an air purifier. The following list of common problems can help you consider which need you want to cater to with the air filter:


If one suffers from asthma or if their symptoms are triggered by odor and chemical pollutants, it becomes imperative to consider an asthma air cleaner or an odor and chemical air purifier. These air cleaners contain added odor and chemical filtration as well as HEPA filters for allergen particle removal. Patients with allergies should also consider an air cleaner’s air change per hour (ACH) rate. ACH refers to the number of times an air cleaner can filter the entire volume of air in the room each hour. An ACH of 4 per hour is considered desirable for such cases.


One should choose an air purifier designed for allergy relief in case they are sensitive to allergic reactions. These cleaner units typically have multiple filters, including HEPA filters, to remove indoor allergens. People prone to allergies should also consider the ACH before buying. They, too, are advised to buy a cleaner unit that has an ACH of 4 per hour.


Smoke air cleaners have been designed to remove smoke and other associated fumes that can put our respiratory system at risk or cause unpleasant odors in the indoor environment. HEPA filters are most suitable for eradicating indoor smoke.

Chemical Sensitivities

One might consider an air cleaner for multiple chemical sensitivities (MCS) if they are extremely sensitive to chemicals. These models contain even more odor and chemical filtration. They are often manufactured with materials that will not give off gas chemicals into the air and aggravate your symptoms.


Some air cleaners are designed specifically for individuals or families with pets. These cleaner units remove pet dander, odors, and hair.

In addition to these factors, it is crucial for us to take into account the right size air cleaners for our needs. Usually, the right size is contingent upon the size of the room. Small air cleaners are designed for personal space or rooms up to 299 square feet. Medium air cleaners are suited for rooms between 300 and 699 square feet. For rooms between 700 and 1,900 square feet, a large air cleaner becomes indispensable. There are also air filtration systems which clean the air of the entire house if they suit your spending capacity.

Lastly, the consumer can look for air cleaners that are energy efficient. 5 star rated appliances help conserve electricity and save on bills. There are also additional features that make the cleaner unit user-friendly such as noise, mobility, smart-phone enabled, air quality indicators, and filter change indicators.

Air filters are not a luxury anymore but a high-value necessity. The global concern about rising air pollution levels is alarming. While there is not much we can do about global pollution, we can still keep the air inside our homes clean and healthy.
