I just checked the air quality in our flat plus it is standing in the excellent range.
I used to have a lot of problems with the air in our flat because of the traffic that goes up plus down our road, but this all changed recently plus I am so happy about it. This wash air is due to the fact that I have HEPA filters in both our air purification system plus our central Heating as well as Air Conditioning system, when before I just had a regular filter in each 1. I bought some legitimately cheap filters online a few years ago plus thought I found the deal of the century. Why I bought so many of them, 100 filters, is beyond me because I ended up throwing away 98 of them because they were so bad. The Heating as well as Air Conditioning dealer I bought them from went out of business, so I couldn’t return them plus they were of such bad quality that I didn’t want to give them to anyone. The filters were so bad that I bet the Heating as well as Air Conditioning system could suck in a fly plus it would pass through the filter plus out of the vents in the rooms! You could actually really pass a golf ball through the filters, they were so bad, haha. The HEPA filters I have now, which are both the washable type, cost a bit more money of course but they labor so much better at removing dust plus odors from the flat. So now our house is a lot fresher plus I suffer way less from our dust sensitivities now.
