Signs Your Window Air Conditioner Filter Needs To Be Changed
If you can’t remember the last time you changed or cleaned your window air conditioner’s AC filter, it’s likely overdue for a change. Still, there are a few signs that can indicate that your filter needs an immediate change.
- The Air Isn’t Getting Cold Enough
Are you waiting several hours for your interior air to reach the desired or set temperature? If so, your window AC unit’s air filter may be dirty.
- Your Electricity Bill Has Increased
One of the most significant signs that your AC air filter is clogged and dirty is increased monthly electricity bills. When your unit needs to work harder to pull in air, it can cause the air conditioner consume more energy by working harder.
- Dust Is Accumulating In The Air Vents
If the vents at the front of your window AC are constantly forming strings of dust or dirt, there’s a good chance that its internal air filter is full of debris.
- You Are Suffering From Allergy Attacks
An increase in sneezing, coughing, or asthma symptoms may also indicate a dirty AC air filter. Remember, your window air conditioner pulls in and blows out air. A dirty filter can increase the number of allergens floating through your home’s air.
- The Filter Looks Dirty
If you take off the front cover of your window AC unit and you can see dirt or dust inside the filter, it’s time to clean or replace it.
Finding, Removing, And Replacing Your Window AC Filter
You might be wondering, “Is the filter of my window AC unit easy or hard to remove?” The answer depends on the precise make and model of your window air conditioner.
For example, some window AC units have a front cover that easily pops off with a bit of pressure along the sides. Others are attached by screws or latches. As such, gaining access to the unit’s air filter could be as simple as popping off the cover, or it could require a screwdriver.
Either way, removing and replacing the air filter is a straightforward process:
- Identify the type of closure your unit uses to keep the cover attached
- Turn the unit off before removing the front cover
- Pop or pull off the front cover
- Identify the air filter; Most should look like a screen with several squares
- Either wash off and dry the current air filter or replace it with a new one
- Be sure that your air filter is secure within the unit
- Replace the front cover and make sure that it’s securely attached
If your window AC unit came with a user manual or owner’s guide, be sure to reference this booklet before getting started. It may contain a more detailed step-by-step set of instructions for air filter maintenance, cleaning, and replacement.
What To Look For In A Quality Window AC Filter
The first thing you’ll want to look for in a quality window AC filter is size. That’s because air filters come in a wide variety of sizes. Choosing the wrong size is bound to lead to frustration and product returns.
Another aspect to consider is the MERV rating. This rating reflects the size of particles allowed to pass through the air filter. The higher the MERV rating, the more airborne contaminants the filter will collect.
However, a higher MERV rating can also impact airflow. That’s because thinner filters make it easier for your air conditioner to pull in air, while thicker options can cause your unit to work harder. Choosing a filter with a rating of between five and eight is an excellent option, as these can capture lots of airborne dust and dirt without overworking your unit.
The best way to determine the right-sized AC filter for your window unit is to look at the size of its current filter. First, of course, you’ll need to open your window air conditioner to find the old filter.
