Replacement Filters

When homeowners are interested in improving their home's indoor air quality, a common purchase they make is an air purifier. Many air purifiers require that you purchase replacement filters periodically, just as you would purchase replacement filters for your heating and cooling system. Since replacement air filters are in demand, there are many different types available. Each filter has different advantages and disadvantages, whether it is for an air purifier or a central heating and cooling system.

Replacement air conditioner filters are available for both window unit air conditioners and central cooling systems. These replacement filters range from inexpensive fiberglass type to high quality allergen-reducing filters. The more allergens and pollutants that the replacement filter can trap, the higher the price. The fiberglass filters, for example, only trap dust and dirt, but not smaller particles such as mold or allergens. The more expensive pleated filters work well to capture dust and dirt as well as mold and allergens. You must follow the manufacturer's instructions for changing your replacement filter in your heating and cooling system or window air conditioner, and change the filter as often as recommended. You may change the filter more frequently if it becomes dirty, as a dirty filter will not be as effective as a clean one. You will need to know the size of your old filter, in order to buy the proper replacement filters.

If you are looking for air purifier replacement filters, you will again find a wide variety of styles available. In the case of air cleaner replacement filters, you will need to know the brand and model number of your air purifier, in order to buy the proper replacement filters. Some filters may fit more than one brand or model, but this is not always the case. For example, a Kenmore air cleaner replacement filter may not be the same as a Sunbeam air cleaner replacement filter, so it is important to know the brand of your unit. You also should know the model number of your unit, because many popular brands such as Holmes replacement air filters or replacement Honeywell air filters will have a large number of different filters, each designed for specific models of air purifiers.

Finally, if you want to forget about replacement filters altogether, there are some air purifiers that require no filter replacement. These come with washable filters that can be reused. You can find air filter replacement cartridges if needed due to damage, but regular replacement is not required.
