When it comes to air filters, one of the most important factors to consider is longevity. Low-cost filters are usually made of inferior materials, such as cardboard and paper, which don't last as long as their more expensive counterparts. This means you'll have to replace them more often, which can end up costing you more in the long run. On the other hand, investing in a more expensive air filter can save you money in the long run.
Washable air filters are some of the priciest options available. These are framed in aluminum instead of cardboard, like disposable filters, and should last for several years. The initial cost of a washable filter is higher, but you'll save money in the long run as they last for years rather than months. However, there are some drawbacks to using a washable filter, such as a lower MERV rating, frequent maintenance requirements, and the potential for it to attract mold to the air unit. When selecting an air filter, look for one with more folds.
This means a thicker filter for particles to pass through, but also more surface area for air to pass through. If you have an unusually sized filter area, some online companies are manufacturing custom filters for those unique systems. An electrostatic air filter is a washable air filter that uses static electricity to capture particulate matter. You may also come across air filters with additives such as activated charcoal and baking soda. These can be beneficial for those who suffer from allergies or respiratory diseases such as asthma and allergic rhinitis.
However, be aware that using a filter with a high MERV rating will increase your energy costs. When it comes to the health and comfort of your family, friends, and other guests, it's a good idea to buy the most efficient air filter you can afford. If you can find a reusable filter that captures the types of contaminants you need to filter for your family, you might pay more upfront but save money in the end.
