Its well worth a read before you click the order button.

The basics first.

What is an air purifier?

What does an air purifier do?

An air purifier (air cleaner to some) is simply a machine thatgets rid of nasty contaminants from the air circulating in your room.

Modern-day purifiers are moreadvanced and provide relief from allergies, asthma, nasal congestions, andmore.

Some of the best air filters for home also deodorize your rooms they will smell fresh.

Types of air purifiers

Its important to understand that air purifiers work differently when selecting the best home air purifier or even an office air cleaner.

Lets go through thecommonest types and how they function:

·        HEPA (High Efficiency Particulate Air) air purifiers

These purifiers use the classic HEPA technology to filterout particles.

The greatest advantage of true HEPA filters is theirefficiency (they typically trap 99.97% of all allergens and other particleseven as small as 0.3 microns).

·        Activated Carbon Devices

You might want to use purifiers with activated carbon(carbon processed with activated charcoal to create small, low-volumepores) if youre regularly breathing in harmful fumes, odors, and chemical gases.

These use a process called adsorption to capture odors andgases and sometimes volatile organic compounds (VOCs) from your environment.

·        UV Light Air Purifiers

Air purifiers with UV light superbly eliminate myriadairborne germs, bacteria, and viruses.

The generated ultraviolet radiation breaks up themolecular structure of these organisms killing or rendering them powerless.

·        Ionizing Air Purifiers (Ozone generators)

Your best home air purifier or office could come with an Ionizer.

These are so-called since they create and deploy charged ions on the hapless airborne particles until they tumble fall from the air.

Some of these generate ozone - to remove odors- and mightirritate your lungs if you have a respiratory problem. 

·        Electrostatic Air Purifiers

These use static electricity to charge airborne particles soas to kill niggling microbes, particulates, mold spores, and more.

Just before I take you to thereviews, here are things you need to keep in mind especially now that youll bemeeting an avalanche of options out there.

·        Your specific needs

For instance, youll want topick a specialized allergen remover if you suffer stubborn allergies while yoursafest bet is a HEPA air purifier ifyoure overwhelmed by pet dander.

And so forth.

·        Your room size

Each unit only cleans specified square footage optimally andyou want to confirm before ordering.

If two units work well for equal footage, check each unitsdust, pollen, and smoke CADR rating.

The CADR simply tells you the number of cubic feet (of air)it can clean in a minute and higher rating mean quicker results.

Consider investing in two (or more) units if cleaningextra-large spaces.
