What To Look For In Advanced Air Purifiers

By Chris Channing

Air purifiers have long been around, aiding families keep contaminants out of the air. Advanced air purifiers go a step further and take more out of the air that may cause illness, allergies, or other negative effects. They aren't cheap, however, so knowing what to buy is important.

Today the average air purifier on the market is going to make use of several filters. The advanced filters are located behind what is called a pre-filter, which is there to catch larger particles or mere dust that would just clog the more finely-woven filters. This also helps extend the lifetime of the advanced filters, since they get less dirty- and allows them to work better for longer, which saves consumers a nice chunk of change.

Typically, the next filter will be a HEPA or SuperHEPA filter. HEPA stands for high efficiency particulate air. HEPA filters are able to clean over 99% of particles from the surrounding air, making them a key choice in air filtration. The SuperHEPA filter expands upon this efficiency, and further improves the filter's ability to remove harmful pollutants.

The OFS filter is usually an optional add-on that helps keep out bacteria, mold, and spores. OFS filters, which stands for organic fiber sterilization, is highly effective in fighting the spread of airborne diseases and infectious bacteria. Like the HEPA filter, it is finely tune to trap out the smallest of air particles, which goes to show that the pre-filter is all but necessary considering the level of precision such filters contain.

It isn't hard to obtain such described filters- even today's modern vacuums have them! Filter add-ons are now being placed on vacuums in order to do a two-step cleaning process. The vacuum removes dirt from ground sources, while filters work to keep the air clean. These filters aren't as powerful as stand-alone systems, and also aren't working around the clock to remove contaminants. Regardless, it's good to find a vacuum with this option to do its part in providing a safe environment.

Before making a purchase of an advanced air purifier, keep a few specifications in mind. It will take a good amount of electricity to power them- consider the wattage rating in regards to your electricity bill. Also find out the estimated costs in replacing filters over the course of a year. Finally, check with the specifications to see how much of a space the air purifier can accurately purify without problems.
