Choosing the Right Type of Home Air Filter

When it comes to choosing the right type of air filter for your home, it can be overwhelming to navigate through the options. Here are some things to consider before making a decision:

Efficiency: Look for air filters with higher MERV ratings (Minimum Efficiency Reporting Value) as they can filter out smaller particles. Consider your home's needs and the air quality in your area when selecting the level of efficiency you need.

Material: Air filters come in a variety of materials such as fiberglass, pleated paper, and washable filters. Fiberglass filters are the most basic while pleated paper filters offer better filtration. Washable filters can be reused for extended periods but require more maintenance.

Size: Make sure to measure your existing air filter or consult your HVAC system's manual to determine what size filter you need. A filter that is too small will not effectively filter air while one that is too large will not fit in your HVAC system.

Budget: Air filters come at different price points. While more expensive air filters may offer better filtration, it's important to balance the cost with the filter's effectiveness and your budget. A higher-priced filter may be a good investment for those with allergy or respiratory issues but may not be necessary for those with standard air quality needs.

By considering these factors, you can choose the most appropriate air filter for your home and improve the quality of the air you breathe. Remember to regularly check and replace your air filter for maximum efficiency.

Measuring Your Air Filter’s Size

Before you start shopping for a new air filter, you need to know the size of your current filter. This will ensure that you purchase a replacement filter that fits correctly and performs optimally. Luckily, measuring your air filter’s size is a simple process that only takes a few minutes. Follow these steps to find out the right size:

  1. Turn off your HVAC system to prevent any air circulation during the process.
  2. Locate your current air filter. It's usually found behind a vent or grille on your wall, ceiling or floor.
  3. Remove your current air filter from its location, being careful not to damage it or release any debris.
  4. Measure the width and height of the filter. If you have difficulty seeing the dimensions clearly, use a measuring tape or ruler.

Frequently Asked Question

When it comes to indoor air quality, a quality HVAC filter is essential. Knowing the different types of filters available for the home is the first step to getting the clean air you deserve. Not all filters are created equal, so it's important to take into account factors like cost and filter size when making a decision. HVAC filter sizes can vary from 10" x 10" to 30" x 30", and the filter's thickness, or depth, is usually 1 inch for common systems and 5 inches for larger systems.

Are air purifiers worth it? Do you need a high-efficiency HEPA air purifier? What about MERV ratings – are they important? If you’re wondering about these questions, you’re not alone. Many people are trying to improve their indoor air quality and are not sure which air purifier to invest in.

We’re here to help shed some light on the subject. Air purifiers, also known as air cleaners, help improve air quality by trapping pollutants and allergens from the air. They do this by using a fan to pull in the air from the surrounding area, then passing it through a filter or series of filters. Finally, the clean air is pushed back into the room.

Air purifiers are designed to trap dust, pollen, spores, and other airborne particles, while also taking care of odors and killing bacteria and viruses. This makes air purifiers a safe way to improve indoor air quality. They don’t emit any harmful chemicals or gasses into the air, making them a great option to consider if you suffer from asthma or allergies.

There are many benefits to using an air purifier. Not only can they reduce allergens in the air, like dust mites, pollen and pet dander, but they can also kill airborne microbes and reduce harmful chemical pollution. An air purifier can also eliminate smoke and odors from cooking, smoking, or fires, as well as remove mold from the air. Furthermore, using an air purifier can extend the life of your HVAC system, leading to lower energy bills and longer lifespans.

In conclusion, air purifiers are a great investment for improving the air quality in your home. Not only do they offer health benefits, but they can also help save you money in the long run. So, if you’re looking to improve your indoor air quality, an air purifier may be worth the investment.

Air filters are an important, yet often overlooked component of your home's HVAC system. They may look like simple cardboard boxes full of fibers, but they play a huge role in indoor air quality and HVAC performance. Here's a quick look at what these filters do and why they are so essential.

Air filters are made up of spun fiberglass, paper, or cloth enclosed in a cardboard frame. Their purpose is to clean the air that circulates through the HVAC system, trapping and holding dust, dirt, pollen, mold, lint, fibers, and other contaminants. Then, when the air is sent back through the HVAC system after it's been conditioned, the filter removes these particles from the air.

Every single bit of air that heats or cools your home will pass through the air filter, so it's critical that it's always clean. A dirty, clogged filter can cause a number of problems, from reduced airflow to HVAC system damage to higher energy bills. That's why it's important to check and replace your air filters every month. 

Simply hold the filter up to a light source - if you can't see the light through it, it's time for a new one.

Absolutely! Indoor air quality can vary from home to home, but most of us spend around 90% of our time indoors, making it essential to ensure the air in our homes is clean. Pollutants such as particulate matter, formaldehyde, mold, and pollen are all common indoor contaminants.

So, what's the best way to improve the air inside your house? Reducing or removing pollutant sources and ventilating with clean outdoor air are the most effective strategies. However, air filtration can also be used to supplement these measures. Portable air cleaners and HVAC filters can both be used to reduce indoor air pollution and improve air quality.

These devices are designed to filter air in either a single room or throughout the entire house. While they are very useful in removing pollutants from the air, they cannot completely clear it of all contaminants. So, if you're looking to breathe easier, investing in a portable air cleaner and/or upgrading the air filter in your existing HVAC system is a great place to start!

Do you know where to locate air filters in your house? If you have a forced air heating or cooling system, then it's likely that your home has at least one air filter. This filter works to get rid of any airborne particles or debris from the air inside your home. To enjoy better indoor air quality, it's advised to replace your air filter every three months. Though, if your home has numerous occupants or pets, you should check your filter at least once a month. When you can't see through it anymore, it's time for a new one. When replacing your air filter, make sure to use the same model number as the one you just took out.

When you want to find the air handler, you'll need to look for a one to four-inch slot. It should either be covered by a removable lid or a wide-hinged lid. Once you open the lid, you should be able to spot the existing filter. Remove the old filter and insert the new one carefully - the filter should have arrows to help you make sure it's inserted correctly. The arrows should be pointing in the direction of the unit.

Homes with larger systems tend to have more than one air filter. After finding the first one at the air handler, you should see a second filter at the return vent. It will be larger than the regular vents and may either be rectangular or square. You may even find air filters in ceiling or floor return vents.
