Choosing the Right Air Filter For Your Ocala Home
Trying to select the right air filter for your Fort Lauderdale home can be a daunting experience. What’s the best one? Does the price reflect the quality? These are just two of many of the questions that make the selection mind-boggling. Let Service Experts Heating & Air Conditioning try to help you de-mystify the air filter dilemma.
Here’s an easy way to figure out how efficient your current filter is (NOTE: Do this outdoors or with something below the filter so you don’t end up with a mess): Position the filter horizontally, then taking common table salt, start pouring the salt through the filter and see the amount comes out the other side. If some or all the salt falls through the filter, then you can assume that the filter will let dust particles of similar size pass through. You really should upgrade your filter to higher quality filter that is more efficient.
There are 3 primary considerations when choosing a household air filter; Size, Material and MERV rating.
1) Filter Size
Unless you have the proper size home air filter, you will never enjoy the full effectiveness your system and filter can provide. Simply look at the label of your existing filter to see the proper measurements, or just measure it yourself. Most home air filters are 1” thick, but there are a variety 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 capture contaminants.
To explain MERV ratings more impactfully, these are some typical MERV ratings and how they relate to efficiencies. This is only a guide, so be sure to read the filter manufacturers’ information when shopping for 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%
Extended pleated
MERV 13-16 >98%
Electronic
Be Careful About High MERV Ratings
While a higher MERV number may offer better filtration efficiency, it is very important to understand that too high a MERV filter may also cost you more to operate your heating and air conditioning system. The higher the MERV, the more restricted 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 probably be a piece of plywood that prevents ALL contaminants and all the air from getting into your Fort Lauderdale home. That’s maximum air filtration, but would also be a terrible way to live.
Your best bet for most systems would be a MERV 6-8. A higher MERV filter should be used on the advice of your Service Experts Heating & Air Conditioning representative to confirm your system has the capability of moving the correct volume of air through higher efficiency filters. You generally 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 needs a high MERV air filter, consider a whole-home air filtration solution that will achieve your energy and filter efficiency needs.
Filtration has changed considerably over the past ten years. Initially, home air filters were used in the furnace or air handler only to protect the comfort equipment itself. The story is different today. Fort Lauderdale area homeowners expect their air filter to save children from a a growing list of harmful pollutants, dust mites, and even prevent the need for dusting. Dare to dream!
