An Easy Fix
Changing a filter may seem like a pain, but it doesn’t have to be. Here are the top six tips when changing filters:
1 Turn off the unit first. This puts your safety first and you won’t risk touching any live voltage. It also helps keep your unit safe. If your unit is still running while you’re removing the clogged filter, dust and debris can enter and cause it to malfunction.
2 Choose the right size. Remove the filters that are currently in place and look at them carefully. Check out a rating system like MERV (Minimum Efficiency Reporting Value). Based on a filter’s thickness it will point you in the right direction (the thicker the better, within limits), as can the brand name or dimensions you find on the filters you’re replacing.
Consider quality carefully. Buy filters that are double framed, which are a higher quality and more durable than the ones found at big-box retailers.
4 Look for any gaps around the filter frame. If there are gaps you may have the wrong size filter, or the filter itself may be defective or damaged.
5 Keep maintenance records. Jot down the date of filter replacement on the side of the filter for the next time you inspect it. A filter that becomes dirty enough to change within a short period of time may mean there’s a problem with the system, so monitoring is important.
6 Inspect filters regularly. Once the filters are installed, keep an eye on them. When they become saturated with dirt and particles, it’s time to replace them. A good reminder is to check them at the start of each season, or every three months on average.
