5 Tips For Buying Air Filters

3M Filtrete Air FiltersThere’s a very good reason that you see more promotions and better deals on air filters during the fall and spring.  Simply, many just don’t think to swap out their air filters until out-of-control allergies force their hand.

In that sense, we know this post is not in any way trendsetting.  We’ll just have to settle for helpful, instead.

As you find yourself in the biannual air filter buying cycle, keep these five tips in mind:

1. Now Is The Time To Buy & Stock Up
Those that sell air filters, including us, know that Fall and Spring are the times you need to buy.  In response, you are going to see some great deals encouraging you to stock-up.  Our advice? Do it.

While now is the time that changing air filters is on your mind, odds are good that you’ll need to replace your filter again before spring, when these deals crop up again.  At a minimum, we’d recommend buying at least two filters to get you to that next sale period.

2. Don’t Wait Longer Than Three Months
Typical lifespan of an air filter is three months.  Check out the image to the left, courtesy of the San Diego Real Estate Inspection Company, for a nasty one that’s clearly gone a bit longer. It’s possible that some filters may need to be replaced more frequently and it’s also possible that a filter could last a miraculously long time.  It depends heavily on the quality of air being passed through.Dirty Air Filter

Even if you don’t find yourself changing your air filter every ninety days, at a minimum, check the filter to ensure it is holding up.  There’s nothing worse than paying more than you should on HVAC maintenance because you went too long between swapping out a $20 – 40 air filter.

3. Better Prices & Deals Are Available Online
Nearly all the big box stores are in the air filters business.  While their prices may be competitive, they will rarely be able to approach the prices online stores like ours are able to offer.

If you are in the market for an air filter this month, we would encourage you to compare our prices on top brands – including 3M Filtrete – against the big box stores.  If you do find a better price, let us know (1-800-683-8353) and we’d be happy to offer a price match if you send the information our way.  Also keep in mind that all orders placed by 4pm CST typically will ship same day.

4. MERV Ratings, MPR Ratings & Thickness: Bigger Not Always Better
It should come as no surprise that at FridgeFilters.com, we pride ourselves on knowing a little bit about water filters.  As such, we oftentimes find ourselves talking customers out of more lucrative purchases, simply because the needs of the customer don’t warrant bigger systems.   With air filter MERV ratings, MPR Ratings and thickness, our advice is similar.

3M Filtrete 4 Inch Furnace Air FilterMERV (Minimum Efficiency Reporting Value) is a score indicating how much dirt, dust and dander the filter captures.  MPR is a 3M term that stands for Microparticle Performance Rating.  Higher scores mean the filter captures more particles.  So why wouldn’t you want the highest ratings available?  The answer lies in your type of HVAC system’s ability to handle higher rated filters.  Higher rated and thicker filters will resist air flow in the process of blocking more particles, and if your HVAC can’t handle it, it could quickly fail.  There’s almost nothing worse than paying to repair, or to buy a new, HVAC system just because of an unnecessarily large filter.

Higher rated and thicker air filters – like the beast to the left – are designed for those with hard-core allergies or significant air quality issues (think heavy smoke and pet dander.)  Most will get by with an air filter with a MERV rating of 11 or lower.

The best thing you can do to determine what type of filter you need is to see what type of air filter is currently in your furnace – and buy the same model.  If you are still in doubt, we welcome you to call our customer service department (that number again, 1-800-683-8353) for help.

5. Air Filters Are Just As Important For Your Fridge
It’s amazing how much funkier dirty fridge air smells after you’ve gone through the effort to swap out your air filters and eliminate dust and dander throughout your house.
