Not changing your air filter can have serious consequences for your health and your wallet. It can cause a range of immediate problems, such as itchy eyes or throat, headaches, and more. In the long-term, it can lead to heart disease, respiratory disease, and even cancer. Furthermore, a clogged filter can cause a 15% increase in energy consumption.
It's important to inspect your filter every month and change it every 30 days. Using an air filter with a MERV rating higher than recommended by the manufacturer of your oven or air conditioner may impair its performance. HVAC experts do not recommend operating the system without a filter in the air conditioner. Dirt can build up in the ducts over time, which means that a good amount of it will most likely enter your home directly and directly into the air you breathe.
This can cause mold to form on vent covers, ducts, and inside the air conditioning controller. The accumulation of particles and contaminants connects to the filter and acts as a blanket that blocks the flow of air. This layer of dirt and dust restricts the amount of air the air conditioner can “breathe”, meaning there is less cold air to cool the house. In general, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days or 3 months.
Personally, I always change my filters every 30 days and recommend the same to my customers.
