I spend a great deal of time at my beach condo doing odds plus ends. I prefer to clean my condo about once per month from top to bottom. I first vacuum the floors of all of the sand that is brought in from the beach. Then I mop all of the floors because the bunch of us track a lot of terrible stuff in from the streets if the two of us forget to remove our shoes. There are a bunch of dogs in this town so you can imagine what gets onto the bottom of your shoes after a lengthy walk. It is not legitimately pleasant. I try to make sure the air quality in this locale is good plus has a legitimately good HEPA filter that removes most of the things in the air that makes myself and others sneeze a great deal. The problem is when the two of us track bacteria in with our shoes, the best air filter systems in the world won’t remove that. I believe it’s a smart move to tell almost everyone to remove their shoes before coming into your household. If you are serious about having good indoor air quality, you should also be serious about having a clean floor because they can cause just as many complications as a terrible air filter. I also prefer to clean all of the windows in the condo every single month plus make them nice plus shiny for the sun to pour in plus light up the household. Every one of us even put an oil furnace filter on our oil furnace to keep any dust from coming out of it.
