So why should I buy an air purifier?

Excellent question! There are many contaminants in your home that you may not have even known existed. They can be very beneficial, especially if you have a home full of furry pets. Not only can they get rid of nasty particles in the area, but they also have the ability to break down nasty odors such as cigarette smoke. Though they don’t have air purifiers that can rid your home completely, 100% free of harmful toxins, they do get pretty close. If you do a good amount of breathing, you’ll probably want that air to be clean. Having an air purifier will be a huge improvement to anyone and everyone without one already.

What does HEPA stand for?

HEPA is “High Efficiency Particulate Absorption”. If you see a HEPA label on an air purifier, it means that it has passed a series of strict guidelines that have been implemented by the US Government. If an air purifier is HEPA certified, this means that it can remove at least 99.97% of air particles 0.3 micrometers or larger. If an air purifier is not HEPA certified, they sometimes only remove as high as 75% of air particles. Essentially, if you have the money and are serious about your air purification, getting one that is HEPA certified is a much better choice.

What is the deal with the UV light attachments?

This is something that is fairly new to the world of air purifiers. Essentially, when particles pass through your UV light air purifier, it not only traps those particles, but also kills germs. It’s a small addition that, while not crucial to a great air purifier, can be helpful.

What is CADR?

CADR is how fast the air purifier can remove certain air particles at the peak of the square footage that it is intended for. Though it is all relative to the space and the machine, if it has a high CADR rate, you can bet that it will work faster than the next one.
