If you're looking for the best filter for your HVAC unit's return vent, then a MERV-5 to MERV-8 pleated air filter is the way to go. This type of filter will serve as the primary line of defense against dust and particles entering your system. For those who want an even more effective filter, HEPA filters are an excellent option. They can trap a wide range of particles, from dust and pollen to mold spores and bacteria.
However, they come with a higher price tag than other return air filter options. Despite warnings that MERV filters 11, 12 and 13 may not be suitable for some systems, there are many owners who have used them successfully for years. The Home Depot also offers a full range of air cleaner accessories to help keep your system running at peak performance. If you're on a budget and only need to capture large particles, then the Rheem indoor air filter is an economical choice.
It has a MERV 5 rating, which is a step ahead of the most basic oven filters available. On the other hand, if you're dealing with air quality issues, supply vent filters will only mask the problem without solving it. To truly improve your indoor air quality, you'll need to invest in a more effective filter. The FilterBuy 16x25x1 Pleated AC HVAC Oven Air Filter is one of the most durable options on the market and can last three times longer than other filters.
It's also rated for medium efficiency MERV filtration, making it suitable for HVAC systems that use coarser filters (usually in the 4 to 5 inch range). If you have pets in your home, then using a return vent filter kit can help keep pet hair out of your HVAC system. However, if there is any erosion inside the ducts, then a vent filter won't be effective as air could pass through the opening. To ensure that your return air vent filter is always clean (or replaced if it's disposable), set up a calendar reminder or check it regularly.
This will help improve the indoor air quality of your home and keep your HVAC system running smoothly.
