Air filtration units still require you to change the air filter

My Mom and Dad decided to buy a small air filtration unit for the house. They haven’t let anyone in doors in several months. They meet my sister and the kids on the porch and they make everyone wear a mask. They don’t hug or kiss the grandchildren and they maintain a distance of 6 feet. My Mom and Dad are both health compromised and the coronavirus could easily kill them. They can’t take any chances right now. They are being extremely safe and I am happy to hear that. I wanted to learn about the air filtration unit that my mom and dad purchased, so I told my mom to send me the make and model. She sent me a link right to the amazon store page. I did some research on the air filtration unit and my mom and dad bought a good one. It uses UV technology to get rid of particles in the air. I might even buy the same air filtration unit for my home. When I talked to my mom about her new purchase, she did not mention that the air filtration unit has a washable air filter. I called my mom the next day to tell her that I ordered the air machine online. When I mentioned the washable air filter, I could tell that my mom did not know that information. Luckily, washing the filter is an easy thing to do and requires very little effort. She decided to look through the handbook more carefully just in case she missed anything else that was important.
