If you did not already know this, air filters that you use in your central heating and a/c system can make a difference in the air quality in your home.
If you have nice quality air filters in your central heating and a/c system you can have better air quality. But when you have cheap air filters that dill up real easy and you forget to change them, this is the beginning of having allergens and poor air quality pumping through the air vents with the heating or the a/c. This is why it is suggested that you buy only the most high quality air filters for your central heating and a/c system unit. A nice suggestion is to buy HEPA brand air filters. Because HEPA brand air filters are the top of the market and of the most high quality when it comes to air filters for your central heating and a/c system. HEPA air filters are a little more overpriced than even the best respected brand air filters, but they are well worth it if you ask me. HEPA air filters even come in washable air filters. With washable air filters this means you can use the same air filter over and over multiple times by simply washing it. This is possibly the best way to save money when buying air filters for your central heating and a/c system. That is what I do and know me it works honestly great! Once you try HEPA washable air filters you will never go back to the old air filters you used.
