The HEPA filter was not working

When I was looking for a way to improve our indoor air pollen levels, all the people advocated to myself and others that I should try a HEPA filter.

The reason is because of the way they work. A HEPA filter works because of its design. The filter has various unquestionably tightly woven fibers that are excellent at catching the smallest pieces of dirt, germs, and debris that would otherwise be floating around in your air and would make you sick. When I first purchased our own HEPA filter it seemed to be working exactly as I’d hoped. I had noticed an improvement in our indoor air pollen levels and everything was going great. However after a few months I noticed that our indoor air pollen levels started increasing again. I could not figure out why because I had the filter, and as far as I knew it should be working. I decided to contact the local HVAC dealer and have a heating and cooling worker come out and see if he could diagnose the issue. When he came in, it took him only 5 minutes to find the source of the problem, the problem was that our filter was now dirty and restrained and needed to be changed and that is when he told myself and others how important it was to change your air filters correctly. I felt prefer such an idiot for not knowing something that was so apparent this whole time. I purchased another brand new HEPA filter and it worked and I had good indoor air pollen levels again.
