Filtrete AOR00-2PK-6E

Clean Carbon-Based Filter

Many types of air filters that are top performers have one thing in common: many of them use carbon-based materials in their construction. Since carbon is quite good at picking up and holding onto small particles, this makes carbon-based filters quite effective.

The active carbon layer on this furnace filter does not leave any traces behind it, so during the installation of the filter the likelihood of getting dirty will be completely excluded. By the way, it can safely be used in conditions of high humidity, so there also isn't a need to worry about humidity affecting the efficiency of the filter.

This filter compares favorably with most other filters of its type in that it is easily able to cope not only with strikingly small particles, but also with unpleasant smells of food or cigarette smoke. Therefore, it is quite relevant for homes where smokers live. If you need a good carbon-based filter that will keep both your furnace and your hands clean, then you can do no wrong with this model.

What Is a Home Furnace Filter?

Just about every home that is located within a climate with cold weather will have a furnace installed. A furnace is the main appliance used to help heat the home whenever cold weather has arrived, and with it often comes a high heating bill, along with various other inconveniences such as bad smells. Furnaces need to be kept in top operating condition so that they can be effective at their jobs of heating a home, and one of the ways to do that is by installing an air filter.

Home furnace filters are a little different than those used for something like central air conditioning. While the purpose of an air conditioning filter is to remove unwanted particles from the air that is blown out through the ducts, a furnace filter is meant to filter the air that is brought into the furnace and heating system. With being able to safely remove debris and other pollutants from the air, this helps keep a home furnace in tip-top shape, ensuring that your home will be efficiently heated. A furnace filter can also have the added effect of keeping the warm air blown inside the home free of unwanted particles as well, thanks to its ability to prevent them from getting into the heating system.

If you are more in need of a spot heater, or if your home does not have a furnace installed, then perhaps you would be interested in finding a ceramic heater for spot heating.
