Furnace Filter Buying Guide: What To Look For?


Your filters’ efficiency heavily relies on its MERV (Minimum Efficiency Reporting Value). ‘The higher, the better,' the same applies to this value as it ranges from 1 to 16. With larger rates comes more entrapment of unwanted and harmful air particles.

However, with a filter that is higher ranked, the furnace is forced to work harder because of the hindrance due to less air flow via it. So when you’re choosing your best air filter for your home furnace, one with high efficiency, a rating of between 8 and 11 is adequate.

2. Filter type.

You’d be surprised at the vast array of designs for filters available on the market right now. What does the description of your filter mean in relation to your needs and expectations?

Let’s take a look at the different types out there and how they can meet your needs and requirements:

  • Electrostatic: From our furnace filters reviews, we’ve seen that if the filter is electrostatically charged, it also acts as a ‘particle magnet.' They come in both disposable and washable types. With the latter, you should also expect it to be quite long lasting almost permanent.
  • Pleated: Bordering on the quantity and quality of air filtration, then this should be a perfect fit. Pleated filters increase the surface area of air filtrated, capturing more particles per inch, unlike other un-pleated designs. Due to this high capture capacity, you’ll need to check and replace regularly.
  • Activated carbon: If you’re looking to kill odors in your residence, then this filter should be the ideal choice. The activated carbon traps odors, fumes, and chemicals when the air passes via the HVAC.

3. MPR

If you’re a 3M customer, then you must have come across this description usually used in furnace filter ratings.

It indicates the Micro-particle Performance Rating of your filter, with the higher the value indicating its superior effectiveness.

Similar to MERV, this shows the efficiency of your filter in capturing particle sizes between 0.3-1 micro (this makes up 99% of air particulates).

4. Filter sizes

Your filter size is dictated and should correlate with the size indicated in your furnace manual. Dimensions are highlighted about the thickness (commonly 1 inch), height and length. Typical sizes as with the ones reviewed above include 14’’x25’’, 10’’x10’’ etc.
