Your Furnace Filter Filtration Basics

Your furnace filter is an important part of your home’s heating system. It’s main purpose is to remove particles and debris from the air entering your furnace in order to protect the mechanical components of your furnace, such as the motor. Here are some basic tips to make sure that your filter is doing it’s job:

1) Check & change your filter regularly – This is typically every 3 months, but more often if conditions require (ex. if you live in an area with a lot of dust, if you have pets who shed, or if you run your furnace fan continuously).

2) Never try to clean a disposable filter – the materials break down over time and are not meant to be reused or cleaned.

3) If your filter doesn’t fit, it doesn’t filter – Air takes the path of least resistance so it is important that your filter fits in as closely as possible. It needs to reach right to the end of the filter track, and there should not be a visible gap on either the plenum or the furnace side. If your furnace needs a specialty size, you should get one, or, get your filter slot changed to fit a standard size. If there is a gap to the sides of the filter and there is not a snug fitting door, using a piece of duct tape down the slot to seal the gaps is a good idea.

4) More “Merv” is not always better – A good Merv rating for residential use to balance particle trapping with air flow is between 5 and 8. You should consult with an HVAC professional before using a very high Merv filter, as your system may not be able to handle the air drop (decrease in airflow) caused by a very high efficiency filter. If you have a 2” or a 4” filter slot, using a filter with a higher Merv rating will be less of a concern, as the higher surface area of a thicker filter causes less resistance to air.

5) Consider Running Your Furnace Fan Continuously – To encourage continuous air flow and filtration, run your fan continuously. Keep in mind that if you have not done this before, you will need to check your furnace filter more regularly, as running the fan will pull more air through the filter and cause it to become full quicker.

Permanent Filter

About the Permatron EZ-Flow Electrostatic Washable Filter

We are proud of the many benefits Permatron EZ-Flow filters bring to your home and your family.

Reusable

This environmentally friendly design means less air filters will end up in the landfill over the life of your air handling system.

Cost Savings

Permatron EZ-Flow’s extended life means there is no need to buy new air filters at every filter change.

Performance

Initial Resistance 0.15″ w.g. @300 FPM (1200 CFM) air  flow. MERV 7 Rating.

Construction of the Filter

  • Air entering and Air leaving – A polyvinyl weaved electrostatic screen creates a trap for dirty particles, stopping them from contaminating your home and your furnace.
  • Frame – A durable aluminum frame, constructed as one piece, will not rust over time as it is washed. The outer frame has holes for convenient draining after washing.
  • Middle layers – The middle layers are composed of a long-lasting polyurethane form, which is durable enough to withstand multiple washes and porous enough to allow for necessary airflow.
  • Center – The center of the Permatron EZ-Flow provides additional rigidity with rust-resistant expanded aluminum metal.
  • Built-in Pull tab – A pull-tab is installed to make it easy to remove the Permatron EZ-Flow.

Installing your filter

  1. Remove the Permatron EZ-Flow Filter from its packaging.
  2. Turn off the furnace fan for your safety.
  3. Remove any previous filter. Wipe down and vacuum, if possible, to remove any debris that may have been left behind in and around the filter track.
  4. On the Permatron EZ-Flow label, locate the directional arrow. Slide the Permatron EZ-Flow into place with the arrow pointing towards the direction of air flow (i.e. point the arrow towards the furnace). Ensure that the Permatron EZ-Flow has a tight seal to prevent any air from by-passing the filter.
  5. Cover the filter track end with duct tape, and mark the last installation date.
  6. Turn on the furnace fan.

Care Instructions

It’s good practice to inspect your filters every 1 to 3 months, depending on the dirt loading characteristics in and around your home.

Washing & Vacuuming Instructions

  1. Turn off the furnace fan. Wear a dust mask.
  2. Place a drop sheet in your working area to collect any debris that may fall off your Permatron EZ-Flow as you slide it out of the furnace.
  3. Vacuum the dirty air side of the Permatron EZ-Flow, and then vacuum the clean air side of the Permatron EZ-Flow, ensuring all lint and dirt are removed. Also vacuum around all drainage holes.
  4. Rinse the Permatron EZ-Flow with running water in the direction against the airflow (against the white arrow), let dry and then rinse in the direction of the airflow (with the white arrow)
  5. Let the Permatron EZ-Flow dry completely before placing it back into the furnace. Reinstall the Permatron EZ-Flow, following steps 4 to 6 in the “Installing your filter”.
