How Do I Know When I Need a New Filter? 

Air filters are a vital part of many different appliances and there are also several of them in your car. 

  • You should take a look at the instruction manuals for everything that comes with an air filter.  Take note of the recommended lifespan of the filter. 
  • Keeping track of the dates that you'll have to replace your air filters on a calendar or your phone is a great way to make sure you don't forget about them. 
  • It's also never a bad idea to check out the amount of dust in any of your air filters.  Even before the manual says to replace it.  
  • Filters in places that have more airborne particles than usual will need to be replaced more often.

How Do I Know Which Filter to Buy?

First of all, make sure that you don't have reusable filters in your vehicle or appliance. If you do, you won't need to buy anything. You'll just need to wash it.  Then put the clean air filter where it was. 

The easiest way to ensure you're buying the correct disposable filters is to buy the same ones that are already in the appliance. You'll know for sure that they'll fit. Indeed, in some cases, you'll have no choice but to go with the single brand that works on your device. 

At times, you'll have options and be able to shop for the cheapest filters possible. You'll want to write down the filter size and dimensions to ensure you get something that fits.
