Do more expensive furnace filters really make a difference?

Expensive air filters are made of higher quality materials, last longer, are more efficient at trapping particles, and have a larger surface area to filter. This can improve indoor air quality and improve health.

Do more expensive furnace filters really make a difference?

Expensive air filters are made of higher quality materials, last longer, are more efficient at trapping particles, and have a larger surface area to filter. This can improve indoor air quality and improve health. When it comes to furnace filters, the general rule for many HVAC professionals is “the cheaper the better”. The main function of an oven filter is to prevent large particles and debris from entering the oven and potentially damaging it.

The cheaper fiberglass filters are just as capable of preventing these larger particles from entering the oven as pleated filters. Basically, any air filter will filter particles from the air before they flow through the entire HVAC system. If you have an unusually sized filter area, some online companies are manufacturing custom filters for those unique systems. More expensive air filters, such as pleated residential filters, filter dust mites, pollen, pet dander, mold, and even bacteria, so it may be worth spending extra money, especially for people with severe allergies.

The cheapest filters are made of spun fiberglass, which does very little to filter air compared to materials such as paper, cotton or polyester. HVAC systems are not designed to improve air quality in the home, and filters are important for the boiler and air conditioner to work properly. You'll notice that it's much harder to breathe if you place the pleated oven filter against your mouth. Washable filters can be cleaned more often if you prefer to keep the filter spotless and, in addition, do not throw the filters into the landfill every time.

Dirty or clogged filters are never good for your system, and if you choose to use an expensive air filter instead of a less expensive one, it can get quite expensive. Plus, pleated filters don't have to be changed as often, just one every 3 months, compared to the monthly frequency of crease-free filters. If all dimensions are the same, a filter with a higher MERV rating and more folds per inch will have the same or better airflow than the same filter with a lower MERV index and fewer creases. Changing the boiler filter once a month is one of the most important general maintenance tasks you can perform for your home's air conditioning system.

By using pleated oven filters, you make your oven work harder than usual to draw in air, since the pleated filter is much thicker. HEPA filters filter bacteria and viruses and are worthwhile for people with serious respiratory conditions, such as emphysema.
