4 Basic Considerations For Selecting Custom Filters

Lots of people make the common mistake of not paying any attention to indoor air quality until it becomes a threat to health. Did you know that the air you breathe indoors is more harmful and more polluted than the air outdoors? Dust, allergens, smoke, and harmful particles can float around your space without you even noticing. These can lead to health problems like headaches, tiredness, trouble breathing, and more. That is why having the right air filtration system in your home or workplace is so important. A good air filter not only protects your health but also helps your HVAC system, including your air conditioning, heating, and ventilation, work better and last longer. Better air means better comfort, better sleep, and better focus throughout the day.

Custom filters are made to fit your specific needs, and that is what makes them stand out. These custom filters are nothing like the standard air filters. These air filters are specifically designed to match your equipment and desired air quality. With the right custom filter, you can reduce energy costs, protect your HVAC system, and improve your indoor air quality at the same time. Whether you are trying to manage dust in a workshop or keep allergens low in your home, the correct filter can make a big difference. There are many filter types out there, and some might look the same but work very differently. That is why it is important to know what to look for before you choose one.

In this blog, you will get to learn about the four essential considerations that you should consider while selecting a custom air filter. You will discover why it is important that you choose the right filter size for a perfect fit, complete understanding of MERV ratings and filter efficiency, a comparison of different materials that are used to make custom filters, and how to select the right air filter for your space and lifestyle. In addition, you will also get to learn about an additional bonus tip on how to properly maintain and replace your air filter.

1. Choosing The Right Filter Size For A Perfect Fit

Getting the right size air filter is one of the most important steps in keeping your HVAC system running smoothly. If a filter is too small, it will leave gaps where unfiltered air can pass through. This not only harms your indoor air quality, but it also allows dust and dirt to collect inside your heating, air conditioning, and ventilation systems. On the other hand, a filter that is too large may not fit properly, and forcing it into place can damage the frame or reduce airflow. That can make your system work harder, leading to higher energy bills and even early wear and tear on your unit.

To avoid these problems, it is always best to measure the filter slot or check your HVAC system’s manual before buying a new one. If your space or system has unique needs, custom filters are a smart choice because they are made to fit just right. A perfect fit helps your filter trap dust, pollen, and other particles more effectively, which keeps your air cleaner and your system working at its best. This also helps lower energy use and keeps your home or business more comfortable.

2. Understanding MERV Ratings And Filtration Efficiency

MERV stands for Minimum Efficiency Reporting Value, and it shows how well an air filter can trap tiny particles. A higher MERV rating means better filtration efficiency, which helps in keeping the air cleaner. For homes, a MERV rating between 8 and 13 is usually a good choice, as it captures dust, allergens, and pet dander without blocking airflow too much. In places like hospitals or factories, much higher ratings may be needed because they deal with more serious pollutants. Choosing the right MERV rating can improve indoor air quality and protect people from breathing in harmful particles.

Selecting the right air filter can also help your HVAC system work more efficiently. If the MERV rating is too high for your air conditioning, heating, or ventilation system, it can block airflow and make the system work harder. This can raise energy bills and wear out your unit faster. On the other hand, if the MERV rating is low, then it will not be able to catch the tiny airborne particles. This will lead to poor air quality. It is essential to find the right balance. A properly rated filter keeps your air cleaner, protects your system, and helps maintain a healthy and comfortable space.

3. Comparing Filter Materials For Better Air Filtration

There are many different types of air filters, and each one of them is built using different materials. Each material works in its own way to clean the air. Some are better for trapping dust, while others help remove smells or harmful gases. Below, you will learn about various air filter materials and how they affect filtration efficiency and indoor air quality.

I. Pleated Filters

Pleated filters were built by using folded cloth or synthetic materials. They are great for homes as they trap small particles like dust and pollen while still allowing steady airflow. These filters work well in HVAC, air conditioning, and heating systems. Pleated filters are more effective than basic filters and last longer, too. They also help improve ventilation and indoor air quality. The only downside is that they may cost more than cheaper options like fiberglass, but they offer better performance.

II. Fiberglass Filters

Fiberglass filters are considered to be the most basic type of air filter. They are built by using spun glass fibers. They are good for catching large particles such as dust and lint, making them a common choice for basic HVAC setups. They are affordable and disposable, but they do not offer strong protection against smaller particles or allergens. Fiberglass filters are not ideal if you are looking to improve air conditioning or indoor air quality in homes with pets or people with allergies.

III. Activated Carbon Filters

Activated carbon filters are specially made to remove odors, smoke, and harmful gases. They use a layer of carbon to absorb smells and chemical vapors, which makes them perfect for homes with pets, smokers, or cooking smells. These filters are not made to trap dust or pollen, so they are often used along with other filters. They are useful in both home and commercial ventilation systems and help make the air feel fresher and cleaner indoors.

IV. HEPA Filters

HEPA filters, also called High-Efficiency Particulate Air filters, are known for trapping tiny particles like allergens, dust, and even some bacteria. These filters are often used in homes with allergy or asthma concerns. They improve indoor air quality by removing 99.97% of particles as small as 0.3 microns. HEPA filters are a good fit for high-performance HVAC systems, but may reduce airflow if the system is not built to handle them.

V. ULPA Filters

ULPA filters stand for Ultra-Low Penetration Air filters. These air filters can remove up to 99.999 percent of particles that are even smaller than what HEPA filters can catch. They are mainly used in locations like cleanrooms and hospitals where clean air is extremely important. ULPA filters can greatly improve air quality, but they are not usually used in homes. They can block ventilation if used in regular air conditioning or heating systems that are not designed for them.

VI. Synthetic Filters

Synthetic filters are made from man-made materials that can be built to trap both large and small particles. These filters offer flexible filtration efficiency and can be used in homes, cars, and even personal masks. They are durable and resist moisture, which makes them a good choice for areas with high humidity. Synthetic filters work well in many types of HVAC and air conditioning systems while helping maintain good ventilation and indoor air quality.

VII. Electrostatic Filters

Electrostatic filters use static electricity to attract and trap particles like dust, pet hair, and pollen. They are reusable and can be washed, which helps save money in the long run. These filters are good at removing allergens and are often used in homes where clean air quality matters. However, they may not catch the smallest particles, so they work best in homes without major allergy issues. They are a solid choice for standard heating, ventilation, and HVAC systems.

4. Finding The Right Filter For Your Space And Lifestyle

Choosing the right air filter depends on more than just the type of filter. You also need to think about your room size, the kind of air you breathe every day, and your specific needs, like allergies or pets. Below are some helpful points to guide you in making the best choice for better indoor air quality, HVAC, air conditioning, heating, and ventilation.

• Measure Your Room Size: To choose the appropriate air purifier size, find out the square footage of your space.. Make sure the filter or machine has enough power to clean the air in your space.
• Know Your Air Quality Needs: Think about what you want to remove from the air, such as particulate matter, pet hair, smoke, or VOCs. Different problems need different air filtration solutions.
• Pick The Filter That Suits You: HEPA filters are great for fine dust and allergens, while activated carbon filters help remove smells. Always base your decision on what is most important in your space.
• Compare CADR Ratings: A higher CADR means cleaner air faster. The CADR should be close to two-thirds of your room size in square feet for best results.
• Look At Your Environment: Custom filters may be needed in spaces with special needs like asthma, strong odors, or industrial activity. Ask about materials built for heavy-use areas.
• Choose Residential Or Commercial Filters Wisely: Filters for homes are not the same as those for large buildings. Commercial areas may need stronger filters due to larger airflow and tougher air conditions.
• Think About Your Budget: Plan for both the cost of the air purifier and regular filter changes. Some filters last longer than others, and that can save money over time.
• Check Noise And Comfort Levels: Some air purifiers are quiet, while others are loud. For bedrooms or offices, a quieter model is often the better choice.
• Consult A Specialist If Unsure: If your needs are unique or hard to figure out, talk to an expert. They can help you find custom filters that match your system and space.

Bonus Tip – Maintenance And Filter Changes

Taking care of your filters is a simple step that can make a big difference in your HVAC, air conditioning, heating, and ventilation systems. It is highly recommended that you should always check your air filters every month. Most of the air filters are required to be changed every 1 to 3 months. However, the frequency of replacement also depends on several other factors, like the overall usage of your system and whether you have pets, allergies, or live in a dusty area. Clean filters help maintain good indoor air quality by trapping dust, pollen, and other small particles. This not only protects your health but also keeps the air in your home fresh and safe to breathe.

Dirty filters can block airflow, forcing your system to use more power to push air through. This can lower energy efficiency, increase your power bills, and wear out your system faster. Regular filter changes are an important part of HVAC maintenance, helping your system last longer and perform better. Whether it is summer or winter, keeping your filters clean will help your air conditioning and heating work smoothly without added strain. Simple filter checks can save you money and prevent bigger problems down the road.
