The Pet Whisperer - 18x24x1 AC Furnace Air Filter

• Industry standard suggests changing your filter every 3 months, BUT… it depends! Many factors determine what cycle is best for you- pets, allergies, how often you run your HVAC system, etc. Some people choose to change their filter every 1 or 2 months.
  
• Luckily, it’s easy to tell when a Yoor Air filter has reached its useful life. After installing your new Yoor Air filter, check it after one month. Pull it out and shine a flashlight through from the coarse filter media side to the Downstream side. If you easily see the light shining through, you still have life left in your filter. Do this for a couple of months and you’ll easily be able to set an appropriate cycle duration. That said, don’t let it go toooo long. If no light is passing through, your HVAC motor is having to work extra hard to push air through your filter, increasing your electric bill and reducing the life of your HVAC unit.
  

• Yoor Air filters have no arrow like you find on traditional, crappy pleated filters.
• Instead, each filter is marked “Downstream”.  This side is installed downstream from the air flow or closest to your HVAC unit.  Here’s another way to think of it.  One side is made of a very coarse filter media while the other side is a tighter weave.  The coarse side catches the big stuff first while the tighter weave traps the small stuff.  We call this Depth Loading Technology and it is the reason The Pet Whisperer 1” filter out lives a high capacity pleated filter by 75%! 

• What’s MERV? MERV stands for Minimum Efficiency Reporting Value as determined by the American Society for Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE).  MERV uses a scale from 1-20. 3M has developed their own standard called the MPR or Microparticle Performance Rating system.  MPR measures a filter’s ability to contain particles smaller than 1 micron and ranges from an MPR value of 300 to 2800.  To confuse us even further, The Home Depot established their own rating system, called the FPR or Filter Performance Rating system which ranges from 4-10 and is color coded.
• What’s Missing?  All of these ratings assume there is no air bypassing your filter.  But, like water, air takes the least path of resistance so a disproportionate amount of air bypasses your filter, technically dropping the MERV rating to 0- YIKES!. Yoor Air filters are designed to eliminate unfiltered air bypass and are the perfect balance between filtering ALL the air while keeping stress on your HVAC motor (measured in air pressure resistance) to a minimum. 
• Consider Microns for a moment - our filters trap particles down to 1 micron - we’re talking dust and mold spores - A human hair is approximately 50 microns and that’s about as small as we can see with our eyes. So yeah, we are talking SMALL!

No air filter can eliminate Covid-19 in your home; however, we do offer the next best thing- a Bi-Polar Ionization system.  This is a professionally installed system that would be in-line with your current HVAC system.  Please email us at hello@yoorair.com to inquire.

Yoor Air filters are made of different layers of polyester filter media custom made to our specifications, an embedded sturdy galvanized metal frame, and an anti-microbial system to eliminate the potential for mold and mildew.

• No, we provide something better! Our 1” filters can replace your wider filters, no joke!  Pleated filters need the extra depth for one reason- dirt accumulates on the surface of pleated filters.  The extra depth increases the surface area and in turn, increases the service life of the filter.
• But, a Yoor Air filter captures dirt and dander throughout the different layers of the filter so we have as much “trapping capacity” as wider filters.  Additionally, the sturdy inner frame stands up to the pressure created in an HVAC system so your filter won’t collapse.  Nor will you experience any “chatter noise” because the extended outer gasket secures your filter in place.
• But what about that extra empty space?  Just think of that extra space as an extension of your plenum.

• First, look at your current filter’s nominal size and order that same size
• If you don’t see a size, if possible, measure your filter TRACK and  shoot us an email at hello@yoorair.com with the dimensions.  Make sure you let us know that these measurements are your TRACK dimensions.  We’ll take it from there.
• If you can’t measure your track, measure your current filter.  Send us an email at hello@yoorair.com stating your filter dimensions. Clearly state these are your FILTER dimensions.  We’ll get back to you with the appropriate Yoor Air filter size. 

• You may have noticed 2 different sizes printed on the cardboard or plastic frame of other brand’s filters. The first is a rounded number like 20x24x1.  This is the nominal size and is used to keep it simple for consumers. The second is the actual filter size measurements and contains fractional numbers such as 19 ⅝” x 23 ⅝: x ¾”.  
• Since we do not have a conventional frame, Yoor Air filters are printed with the nominal size directly on the filter media.

Yes, you can make a single purchase; however, we encourage signing up for a subscription because, speaking from experience, a subscription is the ONLY way to ensure you change your filter on a regular basis.

Go to the Product page on our website.  Under Popular Sizes hit “Enter My Size” and add your specific dimensions.  If you’re still unsure, pop us your question at hello@yoorair.com or call us at 833-YOORAIR (833-966-7247).  We’re here to help.

• To get the maximum life out of a Yoor Air filter, it needs to be installed in a specific direction.  Since we don’t have an external frame, the orientation is printed directly on your filter.
• Downstream. The downstream side goes closest to your HVAC unit.  The different layers of a Yoor Air filter trap different size particles.  Trapping the big stuff first preserves the cleanliness of the next filter layer which traps the next smallest particles, and so on.  The incoming air (referred to as the return air) is the dirtiest air so it gets trapped in the outer filter layer with the loosest weave. The side printed with your filter size and downstream catches the smaller particles and is facing or is closest to your HVAC Unit.
• Upstream.  Your Clean Freak Carbon filter, on the other hand, has your filter size and Upstream printed on the white side because, well, you wouldn’t see the labeling if we printed it on the carbon side!  Your dirty return air comes in contact with the white side first, trapping the large particles.  The smaller particles and odors are contained within the carbon granules.  In this case, it’s the carbon side that is closest to your HVAC unit.
