How to Change Air Filters

Keeping the air clean inside your home is super important for your health! One easy way to do this? Change your air filters regularly. Let's talk about how to change air filters in your home's heating and cooling system. This will help it run better and keep your air cleaner. Even if you've never done it before, you can do it! I will guide you on this essential home maintenance task.

Why Bother Changing Air Filters?

So, why is this task so important? Well, air filters do a lot for your home:

• Better Air: They catch dust, pollen, pet hair, and even mold. This stops that stuff from floating around your house. If you have allergies or asthma, this is really important.
• Happy HVAC System: A dirty filter makes your system work harder. This wastes energy, costs you more money, and can break your system down faster.
• Longer Life: Clean filters stop dust from hurting important parts of your system. This can make it last longer!
• Save Money: A clean filter lets your system run like it should. This means lower energy bills and fewer repairs.

What Kind of Air Filter Do You Need?

There are different kinds of air filters. Each one has a MERV rating. This number tells you how well it catches tiny stuff. Here's a quick look:

• Fiberglass Filters: Cheapest ones. They mostly stop big stuff.
• Pleated Filters: Made of paper or cloth folds. They're better at catching smaller things like dust and pollen.
• Electrostatic Filters: Use electricity to grab stuff. They're good at catching even tiny bits, like bacteria.
• HEPA Filters: The best! They catch almost everything, even tiny things. Hospitals use these.
• Washable Filters: You can clean and reuse them. But, they might not work as well as new ones.

Picking the Right MERV: What MERV rating should you use? It depends! A higher number means better filtering. But, it can also block airflow. Check your system's manual or ask an expert to find the right one for you. Usually, MERV 8 to MERV 13 is good for homes.

What You'll Need

Before we start, here's what to grab:

• New Air Filter: Make sure it's the right size! Check your old filter or your system's manual.
• Screwdriver (maybe): Some filter doors have screws.
• Vacuum (optional): To clean around the filter spot.
• Gloves (optional): To keep your hands clean.
• Marker: To write down the date you changed the filter.

Let's Change That Filter!

Okay, let's get down to how to change air filters! Follow these steps:

1. Turn It Off! Turn off your heating/cooling system. This is important for safety. Find your thermostat and turn it to "Off." For extra safety, switch off the breaker to the furnace and/or AC unit.
2. Find the Filter: Where's the filter? It depends on your system:
   • Furnace: Usually inside the furnace, behind a panel on the side or bottom.
   • Air Conditioner: Usually near the air handler, either in the unit or in a wall/ceiling vent.
   • Heat Pump: Similar to an AC system.
3. Take Out the Old Filter: Open the filter door. You might need a screwdriver. Pull out the old filter carefully. Look at the arrow on the filter frame. This shows which way the air flows. You'll need this info for the new filter.
4. Check the Old Filter: How dirty is it? This tells you how often you need to change filters in the future.
5. Clean It Up (Optional): Use a vacuum to clean any dust from the filter area.
6. Put In the New Filter: Slide in the new filter. Make sure the arrow on the filter points the same way as before! This is very important.
7. Close It Up: Put the filter door back on. Screw it in if needed.
8. Write the Date: Use a marker to write the date on the filter frame. You'll know when to change it again.
9. Turn It Back On: Turn the breaker back on and turn your HVAC system back on at the thermostat.

How Often to Change?

How often should you change air filters? It depends on a few things:

• Filter Type: Thick filters last longer.
• Air Quality: If you have pets, allergies, or live in a dusty area, change them more often.
• Usage: If you use your system a lot, change the filter more often.
• What the Filter Says: Check the filter's instructions.

Here's a general idea:

• Fiberglass Filters: Every month.
• Pleated Filters: Every 2-3 months.
• High-Efficiency Filters: Every 3-4 months.

Check your filter every month. If it looks dirty, change it! A quick look can save you money.

What If Something Goes Wrong?

• Hard to Remove: It might be stuck. Gently wiggle it back and forth. Use a screwdriver to pry it out, if needed.
• Hard to Insert: Make sure it's the right size. Check the arrow direction.
