Product Description
HEPA air filters are made from very tiny glass fibers that are made into a tightly woven paper. This creates a filter consisting of a multitude of very small sieves that can capture extremely small particles, including some biological agents. Once trapped, contaminates and particles are not able to flow back into circulation, due to the highly absorbent pores of the HEPA air filter. HEPA air filters are largely considered the most effective type of air filter for solid particles, such as dust and other allergens. HEPA air filters remove 99.97% of particles down to 0.3 microns in size, almost 300 times smaller than the width of a human hair. The Atomic Energy Commission developed HEPA air filters during the Second World War. They were originally designed to remove radioactive dust from their plants. The U.S. Dept. of Homeland Security recommends HEPA air filters. HEPA air filters are effective for solid and liquid particles, but not effective for gaseous particles. The XJ-3000C HEPA & ionic air purifier incorporates other technologies that are effective against gaseous particles, such as ionization and activated carbon filtration.

Surround Air XJ-3000 Spare Filter Reviews
| 1 of 1 people found the following review helpful  Surround air replacement filter, Amazon Verified Purchase This review is from: Surround Air XJ-3000 Spare Filter (Health and Beauty) This is the replacement filter for the surround air. After I had spent months doing research on different air filtration systems, I did not just look at infomercials. I decided on surround air because it had 5 levels if purification and sanitizing. It was not super expensive. It had a longer warrenty than most. And a very important detail is that it was not expensive to maintain changing filters and such, it turns out to be about $2.50 a month. That seems a fair price to pay for waking with a clear nose and no headache. 1 of 1 people found the following review helpful Awesome smoke eater, By Amazon Verified Purchase This review is from: Surround Air XJ-3000 Spare Filter (Health and Beauty) Any air filtration system is only as good as the filters it uses. If your system takes these filters, you have about the best of the best for allergens, dander and smoke removal short of the condensing units used for commercial purposes. I think it might even do better than those smoke eaters in bars. The ion sanitation will really change the air in your place in less than an hour. I can't recommend this filter enough, my first one is still working perfectly 6 months later at 2 hours a day use. Item as described, By TheRhaja (Richmond, VA USA) - See all my reviews Amazon Verified Purchase This review is from: Surround Air XJ-3000 Spare Filter (Health and Beauty) It's a filter so not much to say, but it was exactly as described and fit my XJ-3000 purifier just as its supposed to. |
