If you don't have your carpet cleaned on a regular basis then you could be exposing yourself to various forms of bacteria and health problems as well. On top of this, you will also find that you can contribute to existing health problems, such as asthma, allergies and more. If you want to avoid these problems then you need to make sure that you have your carpet cleaned every 4 months or so, as this will help to kill any bacteria that might be present as well as making sure that you are as healthy as you can be in your own home.
Bacteria Build-up Think about it, every time you go outside, you bring bacteria in and this can build up inside your carpet without you even knowing about it. You may think that by vacuuming your carpet, you can remove any dust and debris but the truth is that the bacteria still remains and a carpet provides just the right conditions in order for it to thrive. This is especially the case if you have a heater or an air conditioning unit, because heat can make the bacteria grow and an air conditioning unit can carry it around your home.
Dust Mites It isn't just bacteria that you need to look out for, because you also need to look out for insects and dust mites as well. Again, vacuuming really won't affect these creatures and you need to make sure that you have a deep clean if you want to remove both them and the debris that they leave behind. Of course, these can also contribute to allergies as well so it is always a good idea to consider this as an option if your allergies are getting worse or if they are more prominent inside your home.
