Do you wonder who recommends you change your toothbrush every three months? It’s the manufacturers. Those who would benefit most from you changing your toothbrush four times a year. Do you believe them? Until I see scientific evidence to the contrary I am happy to use my toothbrush for a year, or more if it’s still looking good. I use an electric toothbrush and I do take care of it, when you have a £150.00 top of the range Oral B, you look after it! It actually gets treated better than my girlfriend! (She didn’t cost so much!)
Water filters are another thing that can be used more than the manufacturers recommend. Of course they say four weeks will use up the goodness contained in their little filters. Well, that’s based on the filter being used by an average family of four. I’m certainly not average, and I’m definitely not a family of four. I’ll use those filters (instead of bottle water which is about twenty times as much!), for at least six weeks, depending on actual consumption.
Try to overuse things and squeeze the value from every product you use and save those pennies.
