Sharing is caring!

Just like every other system inside your home, the furnace is one that we often neglect until something goes bad, we’ve got no more heat and start fussing over what needs to be repaired. But the costs with repairing a furnace can sometimes be astronomical, depending on what exactly needs fixing or replacing. The best choice would be to make sure that your furnace operates at its optimal levels of performance at all times (in other words, stop neglecting it). And one very good way to make sure that happens is to change the filters on a regular basis. In theory, all is peachy, fine and dandy, but there are so many different filters to choose from, how can you possibly rest assured that you’re making the right choice?

Furnaces & Their Filters

Furnace filter maintenance

The functioning mechanism of a furnace is pretty simple. There are return ducts through which the furnace draws air. This air is then heated by a heat exchanger. Thanks to a blower fan, the heated air is transported through a series of ducts that are connected to the different rooms inside your home. The process is repeated and the furnace will be active until the thermostat inside your rooms reaches the desired temperature.

As you can imagine, the air that is drawn inside these ducts is not at all clean. Several airborne contaminants, ranging from dust and pet dander to allergy triggers, pass through the ducts. This is where the furnace filter comes in. Its primary role is to stop these contaminants from passing any further. This not only helps prolong the lifespan of your furnace, but it also filters the air inside the room so that you can breathe the finest air possible. However, it was primarily designed to protect the blower fan we mentioned earlier. Some furnaces can have furnace-mounted electronic air cleaners which are designed to purify the air inside your home.

How are Electronic Filters Different from Other Filters?

So, while regular, non-electrical models simply sift out the nasty bits in your home’s oxygen during the intake process, an electronic model does that and more. As your furnace operates, passing air through the filter, it collects all the airborne bits and large particles. Then, using an electronic charge attracts microscopic particles like fine dust and allergens that would otherwise pass through into your home’s air.

Why Choose Electronic Filters?

Pros

Cons

  • Traps more dirt and dust
  • Usually, have higher MERV ratings
  • Lasts longer than conventional filters
  • Can be on the expensive side

MERV Ratings & Filter Types

A filter’s MERV rating will indicate the number of different airborne particles that it can block. A filter with a high MERV rating will be more efficient in trapping several different types of particles, but that doesn’t mean that it’s always the best choice. If your furnace isn’t compatible with a specific filter MERV rating, it will work extra to compensate for the airflow blocked by the filter’s fine surface and that could eventually lead to malfunction.

In general, filters with a MERV rating of 8 should suffice for a home, as they can block most contaminants that are commonly found inside a house. MERV rating that goes higher than 13 is generally used in hospitals, clinics, surgery rooms and laboratories, where the air needs to be absolutely contaminant-free if you are to avoid very risky situations.

In order to choose the best furnace filter, you have to understand the differences between the types of filters that are currently available on the market:

  • Disposable filters are commonly used because they provide fewer headaches with the removing, cleaning and reinstalling of the filter. They are generally made from fiberglass and are considered to be of very low-quality, as their MERV ratings don’t usually exceed 4. They aren’t able to block microscopic contaminants and they are definitely inefficient if you or someone that lives with you suffer from allergies.
  • Pleated filters the probably the most common type of filter you’re going to find in furnace systems all across the world. They are neither the best nor the worst type of filter. They are generally made from polyester or cotton paper and their name comes from the fact that the panels have been pleated. The depth of the pleats is generally an indicator of the filter’s efficiency. For example, models that have pleats with depths varying between six and twelve inches are more efficient than ones with lower depths. Their MERV ratings can be anywhere between 5 to 13.
  • Electronic air cleaners (our interest for the day) use the power of electricity to trap particles onto the surface. They are better than pleated or flat filters because they can block a higher number of pollutants. The contaminants are drawn to an electric field that’s powered by high voltage. Once they are filled with an electric charge, they are attracted to plates of opposite electrical charge. The particles will stay trapped to the panel like a magnet until they are cleaned. As you can imagine, the dirties the panels get, the less efficient the system will be. Electronic air cleaners don’t normally have a MERV rating (although, with a little bit of knowledge, you can guess its efficiency).
  • The last category is represented by HEPA/ultraviolet filters. They are considered to be the most efficient filters, as they can block 99.97% of all particles that are larger than 0.3 microns. HEPA filters work based on an exchanging-air principle, which means the number of air exchanges per hour is an indicator of their efficiency. Despite being considered the best type of furnace filters, they are not always the recommended choice (a MERV rating that’s too high can basically be useless, as some of the contaminants it can block are not even present inside your house). Ultraviolet filters, on the other hand, are a component of electronic air cleaners (they can also be sold as add-ons) and they are typically used in hospitals.

      • Lifespan: 10 years
      • MERV Rating: 8
      • Type: washable and adjustable filter
      Check The Price

With a very convenient price tag and full adjustability features, the Eco Plus filter is one of the best choices out there. It can be used on both HVAC, as well as furnace systems, and can successfully trap particles with sizes that vary between 0.3 to 10 microns.

The size of the filter can be adjusted both ways, but it’s important for you to measure the old filter accurately, so you don’t end up cutting too much. Tin snips are the best choice for cutting down the frame, as regular scissors will require an additional effort on your behalf.

With a MERV rating of 8, it should be more than enough in terms of efficiency. However, the surface of the filter may take a longer time to dry, so it’s best to keep a spare at hand, as to avoid using your furnace or HVAC system without a filter.

Who Should Purchase This?

If you’re looking for a washable filter with an adjustable frame, the WEB Eco Plus filter gives you the possibility to trim the filter down to the size that best fits your system.

Pros

Cons

  • 10-year lifespan.
  • Trimmable and adjustable.
  • MERV rating of 8.
  • Made from recycled plastic.
  • Eco-friendly.
  • The surface takes longer to dry.
  • Not mildew resistant.

      • Lifespan: permanent
      • MERV Rating: 8
      • Type: electrostatic washable filter
      Check The Price

There is so much to love about the electrostatic washable filter. This particular product functions just as you would expect, by drawing in the air into the vent system and charging the contaminants with static electricity. The particles are then attracted to the two inches of filter media, which is encased by a four-inch frame.

Whenever you need to clean the filter, all you have to do is turn off your system, remove the filter from its designated place, and then hose it down or vacuum it. The specified MERV rating is 8, which means the filter is efficient in trapping the most common airborne contaminants that can be found in a household.

Because it’s made entirely out of metal, it only takes about half an hour before the filter is dry enough to be put back into your system. However, just to be safe, check the entire surface of the filter for any water residue before sliding it back into its slot. While this particular product is meant to replace 16 x 25 x 5-inch filters, you can always contact the manufacturer if you need a different size.

Who Should Purchase This?

Covered by a lifetime warranty, the AirCare is a sturdy and reliable washable filter that everyone looking to protect their HVAC or furnace systems can enjoy for many years to come.
