There are all sorts of little particulates that are in the air we breathe everyday. For folks with asthma and allergies, having an air purifier inside their home or office space is one way to help make their everyday life a bit better. However, with so many purifiers on the market, choosing the right one can be a challenge. Here are a few tips to choosing the right air purifier for your space.
HEPA- You may be familiar with seeing this acronym on lots of air purifiers and it is an important one. These filters catch 99.97% of particulates that are as small as 0.3 microns. For comparison, the smallest object that a human will be able to see is about 70 microns. There are a lot of false advertisements when it comes to filers so be wary if it says a “HEPA Type” filter.
Noise Level- Depending on where you are putting your filter, the noise level may be of some concern. While they have certainly gotten more quiet over the years, many air purifiers make a gentle humming sound that almost sounds like a white noise machine. Be aware of the level of noise, especially if you are looking at putting it in a shared office.
Understand the CADR- The CADR or Clean Air Delivery Rate, will help you to understand the effectiveness of an air purifier in different size spaces. For example a CADR of 200 for dust means that the air purifier can lower the dust concentration at the equivalent of adding 200 cubic feet of fresh air per minute.
Energy Cost- For an air purifier to stay effective, it needs to run 24/7 to be constantly drawing pollutants out of the air. This may have an impact on your electricity bill so be mindful of the additional cost. Some filters also have an eco conscience mode that automatically changes to standby mode if it does not detect any pollen, dust, or other contaminate in the air.
