• WHICH FILTERS IS THE BEST TO USE IN MY HOME?

  In today's marketplace, higher efficiency filters are available at most retail home stores and homeowners need to be aware that some of these filters (usually in the MERV 11 and higher category) may create low airflow problems in their system. In most cases polyester disposable and pleated filters work the best in homes.

• WHAT DOES EFFICIENCY MEAN?

  (1) The ability of a device to remove particulate or gaseous material from an airstream by measuring the concentration of the material upstream and downstream of the device.
  (2) In the ASHRAE 52.1 Standard test method, it is a measure of the ability of a filter to remove the staining portion of atmospheric dust from the test air. This is officially termed Atmospheric Dust Spot Efficiency.

• WHY DO I NEED A FILTER?

  Nearly every air conditioning and furnace unit includes an air filter used to remove particles from the air that can damage the system and pollute the air in the home. The filter both protects the fans and coils of your furnace from dust build-up that can reduce its efficiency and significantly improves the quality of the household air by removing airborne contaminants.

• WHAT KIND OF FILTER SHOULD I USE?

  You should use an air filter that offers the highest level of efficiency without damaging your HVAC system. Air filter efficiency is the measure of how well the filter does its job of filter air before it enters the air handler. An air filter “cleans” the air by serving as a physical barrier to particles hanging in the air. Manufacturers use a number of materials in air filters, such as fiberglass. Additionally, configuration of these materials can impact the filter’s efficiency. For example, a pleated air filter provides greater surface area to trap particles than a flat panel filter and will thus capture more particles even if made out of an identical material. A wider filter—say, 2” instead of 1”—will similarly capture more particles.

• WHAT ARE MY AIR FILTER DIMENSIONS?

  Air filter sizes come in a variety of dimensions. Most standard filters print the dimensions on the filter frame. You can use those filter dimensions to select the appropriate size replacement filter.
  Unfortunately, some filters are not marked. In this case you will need to measure the dimensions of your existing filter.
  Please also be aware that many filters may have actual dimensions that are not exact whole numbers—for example 17½” x 23¾” x 1”. If this is the case, you should round the fractional dimensions up to the nearest whole number. In the example, this would require a filter with nominal dimensions of 18” x 24” x 1”.

• WHY SHOULD I CHANGE MY AIR FILTERS SO OFTEN?

  There are many benefits of changed your air filters on-time. Here are just a couple.
  Breathe cleaner air in your home, if you don’t change your filters when they are supposed to be changed, the air in your home could be much more polluted than the air outside.
  Save money. Changing your air filter on time can save up to 15% on your heating and cooling bill. Dirty air filters are also the leading cause for HVAC service calls. Not changing your filters regularly can also shorten the lifespan of the second most expensive thing in your home, you HVAC system.

• WHY DON'T YOU SELL CHEAPER AIR FILTERS?

  We promote cleaner air in your home, and the cheap filters just don’t do the job we are looking for. We want you to breathe happy, not dirty.

• WHAT DOES MERV MEAN?

  MERV stands for Minimum Efficiency Reporting Value. That basically means how effective your air filter is. It is scaled from 1-16 and 16 being the highest but we at KLC don’t recommend anything higher than a MERV 13 for residential homes. We like a great balance between filtration and air restriction.
