Buying Home Air Filters 101

Your home air conditioner can easily get forgotten about, yet you take it for granted throughout the year. But forgetting to change the filters of your air conditioner can mean that the system stops cleaning the air as well as it should, while also resulting in the system having to work much harder to warm or cool your home.

A clean air filter removes mould spores, pollen and pet dander, as well as other allergens, from polluting the air in your home. Here are some tips to ensure you choose the right filter for your home and with these filter codes you can get a good deal in the process.

Check the Size

To check the size of the filter you need, remove the existing filter and check the dimensions. This is an important step, as there is a wide variety of sizes to choose from and getting the wrong one will result in your system not working efficiently. The air filter should fit securely and tightly, without any openings on the sides. You should also opt for a thicker filter when possible as this will do a better job of trapping the particles.

Choose the Right Filter Rating 

Air filters are also based on the efficiency with which they clean the air – the minimum rating you should look for is 6, but the top performers are rated 10 or higher. There are also other ratings available, such as MPR which stands for Micro-Particle Performance Rating. The top-rated performers of this particular rating range between 1500 and 1900.

Find the Right Type

Air filters are made from a range of materials, using different methods to trap particles and prevent them from circulating throughout the property. The most common are:

  • Fibreglass filters block out dirt and debris that could others damage your furnace’s motor. While they do remove a small amount of pollen, that’s not the main job of these filters, so they need to be replaced on a monthly basis.
  • Pleated filters are more efficient than fibreglass and can be replaced every three months, so they last longer. The pleats create a larger surface area that means they can catch smaller particles.
  • Electrostatic filters have cotton or paper fibres inside which attract small particles. They’re perfect for homes with smokers or pets, and they’re relatively affordable. They’re also available in disposable or permanent styles, so they can last as long as eight years.
  • High efficiency filters are well-suited to allergy sufferers or people with autoimmune disorders, as they’re extremely effective at filtering contaminants. They use True HEPA technology that leaves your home with a hospital-grade filter.

Change the Filters Regularly

One of the most important things to remember when maintaining the system is to change the filters regularly. They can’t perform to their maximum ability if they are clogged with particles, so make sure that they are cleaned or replaced often to keep the air conditioner working its best. This will not only keep the air in your home as clean as possible but will also help you avoid any costly repairs to your machine.
