Filter fanatics

We’ve all been guilty of not replacing the filters in our lives. This could be because of expense, lack of time or simply the belief that this is an aftermarket money spinner by manufacturers. We generally relate everyday filters to water, the kitchen extractor fan of the vacuum cleaner. And if we didn’t replace these, what’s the big deal, the water is fine from the tap and so it will take a little longer for the kitchen smells to go, we’ll just open the window.
