The Best Air Purifier 2020

In this age of outbreaks you should be mindful of the quality of air you’re breathing in. More often than not, the air we breathe indoors is relatively more contaminated than the air outside.

And since most of us spend most of our time indoors, the constant exposure to low-quality air puts us at a higher risk of contracting health concerns. That is why it’s essential to invest in an effective air purifier that commendably refreshes stale air.

Such an investment will not only reduce your chances of getting health complications, but will also keep your space clean and purified. Even so, few appliances meet these quality standards. Read on to discover 3 of the best air purifiers that are in the market today.

Things to Consider Before Purchasing an Air Purifier

An air purifier is a significant device that saves lives. So, what are some of the factors you should consider before settling on one?

1. Does it have a HEPA filter?

For an excellent air purifier, having a HEPA filter is a must. These High-Efficiency Particulate Air (HEPA) filters are known to remove more than 99.8 percent of 0.3-micron particles. Basically these microns are incredibly tiny particles not visible to the naked eye. For instance, a human hair has a diameter of about 39 microns.

2. Does it match the size of your room?

Another thing to be on the lookout for in an air purifier is a design that serves the size of your space. If you install an air purifier built for a smaller space into a larger one, it will not effectively filter the air.

An easy way to find out the potential coverage of an air purifier is by going through the specification manual. Most reputable manufacturers include this information at the CADR row, which stands for Clean Air Delivery Rate.

3. Noise level

Many people prefer relaxing in total silence or having white noise buzzing in the background. Knowledge of an air purifier’s sound rating is essential as it gives you a better idea of what to expect regarding noise.
