Is it Worth it to Invest in More Expensive Furnace Filters?

When it comes to furnace filters, the general rule of thumb for many HVAC professionals is “the cheaper the better”. However, this isn't always the case. In some situations, investing in more expensive filters can be beneficial. The primary function of a furnace filter is to block large particles and debris from entering the system, which could cause damage to the furnace.

Regular monitoring and replacement is important because old, overly dirty filters restrict airflow and keep your furnace working longer and harder. HEPA filters are worthwhile for people with serious respiratory conditions, such as emphysema. These filters filter bacteria and viruses, providing a higher level of air quality. Cheap woven fiberglass filters do one thing to remove dirt and debris that could damage your furnace blower motor, while removing some of the pollen and mold spores.

However, they don't provide the same level of filtration as more expensive pleated filters. Pleated filters are more effective at filtering out particles, but they also restrict air flow to the furnace. This means that your furnace will have to work harder to push air through the filter. The decision to invest in more expensive filters depends on your individual needs.

A single person without pets and with allergies might not need as much filtration as a family of five with three pets and a child with asthma. Also consider how long your air filter will last. You'll pay more for a washable air filter because it should last for years, instead of months. While it's a good idea in theory, it has multiple problems, such as lower MERV ratings, frequent maintenance requirements, and the potential to attract mold to your air unit. At Filter King we offer affordable filters that look expensive but provide protection equal to what you pay for.

The filter could be in a large inlet vent in the wall or ceiling or directly in the furnace blower itself. HVAC systems are not designed to improve air quality in the home, and filters are important to keep the furnace and air conditioner working properly. If the furnace is the beating heart of your home, air filters are like lungs. Dirty or clogged filters are never good for your system, and if you choose to use an expensive air filter instead of a cheaper one, it can be quite expensive. In general, more expensive air filters are more effective than cheaper ones. However, it's important to consider your individual needs before investing in an expensive filter.
