You’ve probably experienced the feeling of confusion when trying to select the correct home air filter for your needs. What does my system require? Should you just get the cheapest? These are just two of many of the questions that make purchasing air filters for your home mind-boggling. Let Falso Service Experts attempt to resolve your home air filter questions and allow you to continue enjoying the comfort of your home without concern.
Here’s an easy way to figure out how efficient your old filter is (NOTE: Spare yourself a huge mess by conducting this experiment outside or with something below the filter to help keep things clear): Set the filter horizontally, then using common table salt, pour the salt through the filter then see the amount comes out the other side. If some or all the salt falls through the filter, then you can imagine that the filter will let dust particles of similar size pass through. You should probably upgrade your filter to higher quality filter that is more efficient.
Home air filter selection depends primarily on three factors: Size, material and MERV rating.
1) Filter Size
Purchasing a properly sized air filter for your East Syracuse home is important. Simply look at the label of your existing filter to see the height by width and thickness, or just measure it yourself. Typically home air filters are 1” thick, but there are a number of standard width and height dimensions, and some systems have thicker filters.
2) Material & MERV Rating
Filter efficiencies are given a number from 1-16 called the MERV rating. MERV stands for Minimum Efficiency Reporting Value. This number informs the user, under the least efficient conditions, how well the filter is designed to hold contaminants.
To help explain the scale of this system, these are some usual MERV ratings and how they correspond to efficiencies. This is only a guide, so be sure to read the filter manufacturers’ information when purchasing specific filters.
Rating Average Filtration Efficiency
MERV 1-4 60-80%
Fiberglass, Disposable Panel, Washable metal/synthetic, self-charging (Passive)
MERV 5-8 80-95%
Pleated, Media panel, Cube
MERV 9-12 >95%
MERV 13-16 >98%
Be Careful About High MERV Ratings
While a higher MERV number may offer better filtration efficiency, it is extremely important to understand that too high a MERV filter may also require more to operate your furnace and AC system. The higher the MERV, the less the air may flow through the system, and the harder the system may need to work. Your objective should be to get the right balance between air flow, air filtration level and energy efficiency.
Consider it this way, the most efficient ‘filter’ would equivalent to a piece of plywood that prevents ALL contaminants and all the air from coming inside your East Syracuse home. That's maximum air filtration, but would also be the least comfortable way to go.
A safe bet for most systems would be a MERV 6-8. A higher MERV filter should be used on the advice of your Falso Service Experts representative to ensure your system has the capability of moving the suitable amount of air through higher efficiency filters. You probably do not want to sacrifice energy-efficiency for filter efficiency; you want a balance of the two. However, if your family has allergies or respiratory problems and a high MERV rated filter is required, consider a whole-home air filtration solution that will satisfy your energy and filter efficiency needs.
Filtration has changed significantly over the past few years. Originally, home air filters were used in the furnace or air handler only to shelter the comfort equipment itself. Today it’s a whole new ballgame. East Syracuse area homeowners expect their air filter to save children from a whole host of harmful pollutants, dust mites, and even prevent the need for dusting. Dare to dream!
