I don’t know if you’ve ever tried a UV light filter but let me tell you they are entirely great, I have used a HEPA filter for all our air filter & needs for the longest time however I decided to try a UV light filter after our local heating & a/c contractor ran out of HEPA filters.
I tried to change our HEPA filters fairly often to keep them scrub & keep our indoor air pollen levels in wonderful shape.
Unfortunately for me, the HEPA filters are pretty popular so it is not weird for the local heating & AC corporations to go out of stock of them. I asked the Heating, Ventilation & A/C professional when I was there what I could do instead of using a HEPA filter & She suggests that I use a UV light filter. She explained that the UV light filter works by killing the germs on contact, & the only thing you have to worry about is decreasing the bulb. I thought it was worth a try & so I decided to purchase the UV light filter, after all it would be a while before they had no HEPA filters in stock. To our surprise, I found that the UV light filter worked just as efficiently as the HEPA filters. The UV light filters are now our go-to backup whenever I don’t have any HEPA filters available. If things keep going the way they are going I just might start using the UV light filters instead. I love the fact that the UV light is guaranteed to kill the germs the moment it comes into contact with them, whereas with HEPA filters there is still a opening that some microscopic particles could get through & into your indoor air.
