Tips for choosing the right Room air purifiers for you

How to Choose the Best Air Purifier

We spend most of our time indoors. Exposure to poor air quality puts us at risk for ailments. The following factors can help you determine how to choose the best air purifier.

Size of the Room

Always consider your room size before you buy an air purifier. See the following to get an idea.

  • Small: These are designed for rooms up to 299 square feet
  • Medium: Find one for rooms between 300 and 699 square feet
  • Large: Use these in rooms between 700 and 1,900 square feet

Noise

Air purifiers should always be running, and they should also be quiet. You should be able to live with it peacefully. The noise levels should be considered during the high-speed and low-speed settings.

Cost of replacement filters

As a general rule, you should replace filters or clean them every 6 to 12 months for pleated filters and every 3 months for activated carbon filters. The costs of filters vary widely, so choose wisely.

Certifications

There are a couple of labels you may want to look for. One is the Energy Star logo, which saves up to 40% than general models. Then you should consider models with HEPA filters or High-Efficiency Particulate Air filters. These are proven to eliminate 99.97% of common airborne allergens. Next is the AHAM Verified seal. It means that the Association of Home Appliance Manufacturers has tested the model. It provides Clean Air Delivery Rates (CADR) and room size guidelines. To understand the rating see below:

CADR Rating
Above 240 Excellent
180-240 Very Good
120-170 Good
60-119 Fair
Under 60 Poor

Price

It is another factor for consideration. Not necessarily higher priced air purifiers are the best. You can get good features in some mid-range models too.
