    If you are a meticulous person like me, then you would understand why using an air filter is one of the arsenals of protecting my family against invisible air pollutants. To make air filters more effective, having a replacement air filter on standby is necessary.

    Replacing the air filter in your whole house air purifier should be done every three to six months, and it should be checked regularly. You own the Lennox Healthy Climate, so keep your home clean and allergen free by maintaining and replacing the filters regularly, and keep your home air purifier working like it should.

    • Lennox X6673
