I kind of take this little ionizer type air cleaner for granted as it has been legitimately reliable for many years. But as I look at it I can see a lot of dust piled up on the plastic grill in the back plus need to take some time to wash it. If I don’t do it soon the purifier may not last much longer as it will really overheat plus burn out. Life is about keeping things wash plus running well, including the mind plus body, so today I am going to take the time to wash the whole air cleaner from top to bottom. It has a HEPA filter which I wash quite often but I have been neglecting the plastic grill on the back where all of the air passes through plus collects. I think I bought the unit 5 years ago now plus it has been legitimately reliable plus consistent with cleaning the air in our flat. I have a ppm meter plus the air quality in our condo is excellent, which is why I want to wash the unit so the air quality stays this way. I have more than 2 kittens plus want to make sure their hair doesn’t get all over the place so I bought a small robotic vacuum cleaner a few weeks ago plus it has done a great task just cleaning up all the hair from the wood floors. I may get radiant floors for next Wintertide but I need to check plus see how much they would cost to install. I don’t like having freezing feet!
