Are you looking for an air filter that can provide the best protection for your HVAC system and improve indoor air quality? If so, then a more expensive air filter is the way to go. But if you're on a tight budget, a cheaper option may be the better choice. A washable air filter is more costly, but it should last for years instead of months. While this sounds great in theory, there are some drawbacks to consider.
These filters usually have lower MERV ratings, require frequent maintenance, and can attract mold to the air unit. When it comes to furnace filters, many HVAC professionals agree that the less expensive option is the better choice.
