There are tons of quality air filters out there! Your air filter can target your homes air quality or just take care of the Heating, Ventilation and A/C unit. Some air conditioning filter can be reusable others are not. You also can decide what type of material the air conditioning component filter is made out of. Obviously, each model will have features that are more appealing than others. It is up to the homeowner to decide what they want in an air filter. A benefit of the HEPA filter is it has smaller holes in it. This means more dust is caught before it goes into the Heating, Ventilation as well as A/C system. However, the downside is with the smaller holes, the HEPA filter needs to be changed every two weeks. It is also double the cost of the other air filter models. I recently tried a washable air filter. The benefit is that this filter is meant to be used 2-3 times. The air filter also lasts around five weeks before you need to clean it. So that means I would get around several weeks worth out of a single air filter. I thought I was being so smart with this filter, and no, it was not the best for air quality or the Heating, Ventilation as well as A/C, but I believed that I could endure it. The downside of this filter was the cleaning process. According to the instruction, you take out the filter as well as wash it under warm water. It sounds so straight-forward. The process was way more involved. I had to rip it out of the vent, remove the metal coil, get a special tool to clean it, as well as then set everything back up again. It took myself and others over an minute to do it!
