5 Things you must consider while buying an Air Purifier

Air quality has a massive impact on our health. Exposure to contaminated air can lead to serious health issues such as allergies, asthma, and other respiratory problems. An air purifier is considered a smart way to clean air. By removing pet dander, mould spores, ragweed, and more, air purifiers help in maintaining a healthy environment. Since a virus needs to be attached to something like a piece of mucus or a piece of dust in the environment, the air purifier catches those and holds them there. Thus, reducing the risk of transmission. Since a variety of air purifiers are out there, it is perplexing to find out which one can help you.

Air purifiers are designed for specific purposes. For allergies and eczema, purifiers come with multiple filters to remove allergens while for those who are suffering from asthma purifiers have filters that remove allergens, in addition to odour and chemical filters. Some purifiers have specific filters for smoke, pets, and chemical sensitivities.

Things you should consider before buying an Air Purifier

Purpose of the Product (Air Purifier)

It is recommended that you should be very specific about the purpose while buying a purifier. Some of the air purifiers are designed for specific needs like Allergies, Asthma, Smoke, Pets, & Chemical Sensitivities. Purifiers with HEPA (High-Efficiency Particulate Air) filters are perfect to eliminate microscopic pollutants like pollen, dust, mould, bacteria, and pet dander. When used with activated carbon filters, they help in removing harmful chemicals and gases from the air. Electrostatic precipitators and ionizers release charged particles into the air so that pollutants can cling to them and can be pulled to the purifier. However, these electronic types of filters can create ozone can damage the lungs and can cause chest pain, coughing, shortness of breath, and throat irritation. So, consider only those that have been tested and proven to not produce ozone.

Size of Air Purifier

Purifiers are available in different sizes as per their coverage area. Picking up the right size is important to make the best use of purifiers. If you pick up a small one, it won’t filter the air adequately. Selecting too large consumes too much electricity.

Air Purifier Size Guide

Medium – Perfect for rooms between 300 and 699 square feet.

Large – You can use these in rooms between 700 and 1,900 square feet.

ACH of Air Purifier(Air Change per Hour):

ACH signifies a number of times the purifier can clean the total volume of air in a room within an hour. In case of allergies or asthma, you should consider the air change per hour (ACH) rate of an air purifier. Purifiers that facilitate air cleaning at least four times per hour are best for allergy- and asthma sufferers. However, devices with a rate of more than 4 ACH are effective in removing microscopic allergens which can be harmful to health.

Clean air delivery rate (CADR):

It is a measure of the air purifier’s efficiency. We can say how much clean air it can deliver in a room of a specific size. Choose a device with a higher CADR because it purifies the air at a faster rate.

Noise Ratings:

If you require to run your air purifier throughout the day and overnight, noise could be a potential problem. Consider buying a purifier that has a noise rating of less than 50dB. It will not disturb your sleep.


These are some points that can help you find the best air purifiers as per your unique requirements. You can also consider additional factors such as maintenance costs, warranty, manufacturer’s reputation, & service availability.
