If you're like most homeowners, you depend on your air conditioner to keep your home cool and comfortable during the hot summer months. But did you know that your AC depends on its filters to keep running smoothly? Choosing the right filter size can make all the difference in your air conditioner's efficiency and lifespan.
In this post, we'll break down the top AC filter sizes you need to know about. From standard sizes to custom options, we'll cover everything you need to know to keep your air conditioner running smoothly and effectively all summer long.
THE MOST COMMON AC FILTER SIZES
When it comes to purchasing air filters for your AC unit, it's important to know which sizes are most common. This knowledge will help you avoid the hassle of searching for hours or ordering the wrong size online. Below are some of the most commonly available AC filter sizes:
1. 16x20: This size is one of the most frequently seen in stores and online, and it's commonly used in smaller residential units.
2. 20x25: Another common size that can be found in most stores, this filter is often used in larger residential air conditioning systems.
3. 24x30: This size is primarily used in commercial settings and may not be as widely available in stores. However, it can easily be found online.
4. 16x25: This size is commonly used in newer residential AC systems and is widely available in most stores.
5. 14x20: This size is less common but can still be found in some stores or online. It's typically used in smaller, less powerful residential HVAC systems.
Remember that these are just a few of the most commonly found sizes. Before purchasing a filter, always double-check your AC unit's manual or consult with an HVAC professional to ensure you are getting the right size and type of filter for your system.
MEASURING YOUR FILTER FOR NON-STANDARD SIZES
If you have a non-standard air conditioning unit, measuring your filter correctly is crucial to finding the right size. First, turn off your unit and locate the filter. Use a measuring tape to get the exact dimensions of the filter: width, height, and thickness. Make sure to measure to the nearest 1/8 inch for accuracy.
If you find that your measurements don't match up with standard sizes, don't fret! Many companies offer custom filters in non-standard sizes. Some companies will allow you to input your dimensions on their website, and they will create a filter to your exact specifications.
If you're having trouble finding a company that offers custom filters, consider using filter media material instead. Filter media material is sold in rolls that you can cut to fit your specific filter size. This is a convenient option if you need a filter that doesn't exist in standard sizes or if you want to save money by making your own.
With the right measurements and some creativity, finding the right filter size for your non-standard air conditioning unit can be easy and stress-free. Don't hesitate to reach out to companies that offer custom filters or try using filter media material to create the perfect size for your unit.
UNDERSTANDING MERV RATINGS
MERV stands for Minimum Efficiency Reporting Value, which refers to the effectiveness of air filters in capturing and removing particles from the air. The rating system ranges from 1 to 20, with higher values indicating greater filtration efficiency.
Filters with a MERV rating of 1 to 4 are considered basic and can capture debris such as dust, pollen, and carpet fibers. Filters with a rating of 5 to 8 can trap smaller particles like mold spores and pet dander. Filters with a rating of 9 to 12 can capture even smaller particles like lead and legionella bacteria. Meanwhile, filters with a rating of 13 to 20 can trap particles as tiny as tobacco smoke and microscopic allergens.
CHOOSING THE RIGHT MERV RATING FOR YOUR NEEDS
The right MERV rating for your filter will depend on your specific needs. For instance, if you have allergies, you may want to choose a filter with a higher MERV rating to capture more allergens in the air. However, filters with high MERV ratings can also restrict airflow and strain your HVAC system, leading to increased energy consumption and maintenance costs.
It's also important to consider the air quality in your area. If you live in an urban or industrial area, you may need a higher MERV rating to capture more pollutants like smoke and exhaust fumes. On the other hand, if you live in a rural area with little pollution, a lower MERV rating may suffice.
Lastly, consider your budget. Filters with higher MERV ratings tend to be more expensive than basic filters, so choose a rating that balances your filtration needs with your budget constraints.
Overall, understanding MERV ratings can help you choose the right filter for your HVAC system and maintain cleaner, healthier air in your home or office.
SPECIALTY FILTERS: IMPROVE YOUR HOME'S AIR QUALITY WITH HEPA AND ACTIVATED CARBON FILTERS
If you or someone in your household struggles with allergies or has unique air quality concerns, standard AC filters might not cut it. That's where specialty filters come in, offering targeted solutions for specific air quality issues.
HEPA filters are designed to capture extremely small particles like pollen, pet dander, and even tobacco smoke. These filters feature a dense, pleated design that traps particles as they pass through, leaving you with cleaner air to breathe. Activated carbon filters, on the other hand, are used to remove odors and chemicals from the air. The carbon in these filters is treated to create a porous surface area that traps chemicals and volatile organic compounds (VOCs).
If you live in an area with high levels of pollution or wildfire smoke, you might also want to consider a filter with a MERV rating of 13 or higher. These high-efficiency filters can capture fine particulate matter, helping to reduce the amount of pollution that enters your home.
Ultimately, the type of specialty filter you choose depends on your specific air quality concerns. Consult with an HVAC professional or do some research to determine which filter will best meet your needs.
Investing in a specialty filter can help improve the air quality in your home, making it a healthier and more comfortable place to live. Plus, with a cleaner system, your AC unit will run more efficiently and require less maintenance over time.
Consider upgrading to a specialty filter today and breathe easier knowing you're taking steps to protect the air you breathe.
MAINTAINING AND REPLACING YOUR AC FILTERS
Now that you know the top AC filter sizes, it's important to maintain and replace them regularly to ensure optimal functioning of your HVAC system. Follow these best practices:
How often to change your filters: The frequency of changing your filters depends on several factors including the type of filter you're using, the level of air pollution in your area, and your air conditioner usage. As a general rule, it's recommended to change your filters every 30 to 90 days.
Signs that it's time for a replacement: If you notice the following signs, it's time to replace your AC filter:
- Reduced airflow
- Unusual noises coming from your HVAC system
- Inefficient cooling
- Dusty air and unpleasant smells in your home
- Dirt buildup on the filter
Proper disposal of old filters: Since AC filters contain contaminants and allergens, it's important to dispose of them properly. Seal them in a plastic bag and dispose of them in the trash. Alternatively, you can contact your local waste management company for their guidelines on disposing of filters.
Follow these best practices to prolong the lifespan of your HVAC system and ensure clean air in your home.
CONCLUSION
With so many different AC filter sizes available on the market, it can be overwhelming to determine which one is right for your HVAC system.
