I recently discovered HEPA air filters, these air filters are definitely the best for my central heating and cooling system.
The only thing with these HEPA air filters is that they cost a little more than the standard air filters that I used to buy, but paying a little extra for these definitely great air filters goes a long way.
Because HEPA air filters last much longer than the standard air filters, then also HEPA air filters make the indoor air quality of my home stay longer than the standard air filters did, however it is by no means anything like having a whole home air purification plan or even a portable air purification system. But HEPA air filters make it so that you do not even have to think about air purification unless you have bad air quality going on outside. That would be the only way. I am highly impressed with these HEPA air filters for my central heating and air conditioner plan unit. I would never go back to the air filters that I used to buy because these HEPA air filters are simply the best! I can tell you that once you try these things you will feel the same way that I do. They also have washable air filters available in the HEPA brand. I may end up trying those washable air filters out eventually too. Because those will be even more bang for your buck by being able to use them numerous times before having to buy replacement air filters.
