I found a washable HEPA filter for my little robot at the local business and bought a sheet of it.
The filter is actually a big roll of material that you can cut to size.
The roll is made of a HEPA filter material and I am going to use it for both my central HVAC system and my robot floor cleaner. I can also cut it to fit the exhaust fan in my kitchen so it helps to get rid of some of the smells while I am cooking food. I will have a new flatmate soon, a local business owner, who is going to be spending most of her time at work. This will give me a lot of free time at home, which is great because I have been living on my own for almost a year and like my peace and quiet time. She is a meditation and yoga teacher and also sells indoor air quality machines to people for their home and office. I think this will be great for me because it will lower my monthly expenses a lot but I will also still have a lot of my quiet time at home when I need it. I will do some air duct cleaning next week so she isn’t bothered by any dust that may be inside of them. I do have a good HEPA filter in my HVAC system, but it would be a good idea to clean the ducts so that the dust doesn’t keep clogging up the filter all of the time.
