For allergy sufferers and fans of clean indoor air, filters are an essential part of life. Without the air filters in our tiny apartment spring would be even less bearable than it already is and we thank our lucky stars for their presence in our home. However as much as we love our air filters we admit that we are not awesome at knowing when to replace them. Is it the same guideline for the fan as it is for the HEPA, what about the AC?
It's always a good idea to keep appliances and tech dust free, but restoring the air filter to peak condition is one step beyond. For some fans, the air filters can be cleaned and you're good to go, for other appliances, like HEPA filters, a whole new filter is needed. All numbers given are estimates and will vary depending on how often you run the appliance, vacuum the exterior, or if you have pets or suffer from allergies.
The Air Conditioner:
If you do not suffer from allergies or have pets and do vacuum the dust from the AC frequently you should replace the filter in your AC every 6 months. If you suffer from allergies or have pets, consider replacing every 2-3 months.
Again factors like suffering from allergies or having pets will mean you need to replace your air filter more often, however a good rule of thumb for most HEPA filters is to replace them every 3-6 months (at least once during peak allergy season). Check with the maker of your HEPA unit for details, many have pre-filters that if replaced frequently can extend the life of your HEPA filter.
Fans with Air Filters:
Depending on the make and model of your fan, give it a thorough take apart vacuum cleaning every 4-6 months. Its a good idea to give it a less thorough cleaning of the exterior and blades at least once a month especially if you suffer from allergies or have pets.
