Going Shopping For Handy 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.

Air purifiers work based on filters. It isn't uncommon to see the average air purifier have three or more filters, all geared at trying to remove particles from the air that are unwanted. The first filter on an advanced air purifier is always the pre-filter, that is able to get larger particles out of the filtration process so as to not clog the more advanced filters with simple dust. This pre-filter saves money in the long run, as it enables advanced filters to run cleaner for long periods of time.

Recent innovations in air filter design include HEPA and SuperHEPA. A HEPA filter is simply one that is extremely efficient in removing particles in the air- with a rating of over 99% in removal. The SuperHEPA, as one could likely tell from the name, is the successor of the HEPA filter, and is made to take out a wide array of particles through an even tighter filtration process.

Organic Fiber Sterilization, or OFS, is another type of filter that usually precedes more delicate filters. The OFS filter is sometimes considered optional in filter design, but it is quite useful in removing bacteria, mold, or spores from the air. This alone may account for preventing disease or illness that one would otherwise catch from airborne contaminants. The filter is usually placed behind a pre-filter in order to save it from wear and tear.

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.

Final Thoughts

Obtaining an advanced air purifier is easy- they are easily found in convenience stores, health stores, and even sports stores. If you think that an advanced air purifier seems like it would be worthy of your investment, shop around to get a good deal on an efficient model. - 14130
