I used to worry about my air quality; Back in the day when I had a furnace that used air duct, air quality was a major concern, but the furnace was always dusty plus so were the air ducts.
The furnace then blew air plus the dust leaked all over the location, but i was always inhaling harmful indoor air conditions plus getting sick.
I would have to get air duct cleaning every year plus never forget professional heating service, however even with this, I would still feel sick plus exhausted due to my air quality. I thought about UV lights, air purification plus investing in a humidifier to help my indoor air conditions. But, thankfully the heating system died before this happened, and rather than get another furnace, I went with heated flooring. I removed all the old, dusty carpets plus updated with tile. Before the tile went down, electric heated mats went first, with this heating device, no air is blown. It is just electric heat under the feet, however since there is no air or air duct used, the air quality is so much fresher. I also don’t have to worry about dry air quality with the heating system being on. The air feels cleaner plus much more natural, and another bonus is that the heated flooring is totally silent in operation plus none of the heat rises to the ceiling, then not only do I like the heated flooring way better, however it is twice as efficient as that aged furnace system. I feel it was meant to be that the furnace device prematurely died. So cheerful I went with a new idea over buying air quality devices.
