Living in a large city means that you & your family are being exposed to airborne contaminants daily. In such situations, having an air purifier at home becomes a necessity. Today, almost every home has a water purifier, which was once considered as irrelevant a home equipment as an air purifier. With more awareness and adverse effects of unhealthy water, more consumers started focusing on the long-term impact of unfiltered water on their health. Similarly, with air pollution getting more obvious in terms of its ill effects of peoples’ health, more consumers now understand the idea of having an air purifier in their homes. Here’s a buying guide for you to choose the best small air purifier for home:

Why do you need an air purifier?

As we spend more time indoors, we often overlook the air quality. The indoor air contains numerous tiny microbe sized items that can have diverse effects on our health. These range from allergies, flu etc. among other serious health conditions. That is why it is advisable to have air purifiers so you and your family can breathe in clean air.

How does an air purifier function?

• Fans pull in air

Air purifiers contain fans that perform the function of pulling in and pushing back air. In between, the air flows through filters that capture pollutant particles such as pollen, dust and pet dander etc.

• Pre-filters

Pre-filters catch human hair, pet fur, and other large particles from the indoor air before the main filter. While some pre-filters are washable, most are disposable. You are required to change your pre-filter as per the manufacturer’s recommended timeline.

• Main Filter

The particles that make it past a prefilter, then passes through the main filter. The gold standard for air purifiers is a High-Efficiency Particulate air (HEPA) filter. HEPA filters have been known to remove 99.97% of particles that are 0.3 microns in size or larger.

Type of Filters:

• True HEPA filters can remove 99.9% of all the particles which can be as small as 0.3 microns.
HEPA air purifier filters have to be changed from time to time.

• Activated Carbon Filters are used in combination with other filters. These filters help in absorbing odors, gases, and neutralize smoke, chemicals, food smells, fumes etc. Carbon filters also need to be replaced over time.

• Anti-bacterial filters, as the name suggests help in eradicating harmful bacteria and germs.

• UV filters are often used in hospitals, day care schools etc., to minimize the risk of airborne infections.

• Then there are Charged Media Filters that combine particle filtration along with an electrostatic charge filter that has the ability to filter out particles as small as 0.1 microns.

• A Photocatalytic Oxidation filter uses a titanium dioxide coated metal plate along with UV light to oxidize and physically break down chemicals as part of the filtration process.

Important things to note before swiping your card!

• CADR ratings: CADR is the measure of delivery of purified air by an air purifier at its maximum speed setting. Higher the CADR, higher is the purification efficiency for a given room size.

• Air change rate of an air purifier: This element indicates exactly how many times the air purifier filters the air in the room per hour.

Buying an air purifier for your home is certainly an investment. To get the best air purifier for pollution, make sure you keep in mind these aspects and ensure a healthy indoor environment for you and your family members.
