5 Factors to Consider When Choosing Air Filters for Your Home

Your HVAC is an essential part of your home. Not only does it keep your household comfortable, but it also creates a healthy environment for your family. Filters help to remove air impurities such as dust and pathogens for clean and fresh air. Filters can last for several years, but it’s recommended that you change them regularly for maximum efficiency. If you are looking to buy an air filter for your home, below we share five factors you should consider.

1.    Original vs. aftermarket

Whether you want to buy air filters online or at a physical store, you will come across two types: original and aftermarket filters. Both are equally efficient, but they have distinguishing features that you may want to know. Original filters belong to the same brand as the air system, and are made by manufacturers of air systems for use with their models. On the other hand, aftermarket filters are made by independent manufacturers for use with existing air systems. Though they may be the same in design and quality, aftermarket air filters are usually cheaper than the original ones. When selecting filters for an air purifier system, ensure compatibility with your specific model for optimal performance and air quality maintenance.

2.    Size

Knowing the size of the filter your system needs is essential. Most filters have size specifications labeled on their surface, but sometimes the measurements are rounded up. If you’re buying a new model, consider using a measuring tape to get the actual width, height, and length of the unit you need.

3.    Type of air filter

There are different types of filters in the market including, high-efficiency particulate air (HEPA), carbon filters, electrostatic filters, electronic filters, etc. Further, there are different models under each of these categories and each of them is designed to meet specific needs.

For instance, you may go for flat-panel or pleated filters if you’re after an affordable solution that’s easy on your pockets. If you have allergies such as asthma, a HEPA or electrostatic filter may be ideal for you, as they are good at removing microscopic allergens. Similarly, if your interiors are poorly ventilated and tend to trap odors, carbon filters will be the most ideal.

4.    Air quality needs

Air quality needs vary from one home to another. For instance, if your home is highly insulated, it may tend to trap pollutants. Similarly, people with breathing issues and other allergies may require a higher quality filter for efficient air purification. According to research, Americans spend about 90% of their time indoors. Hence, getting filters that guarantee high-quality air for your specific breathing needs is essential.

5.    Filter performance

Filters are rated based on their performance and some have a minimum efficiency reporting value (MERV) rating, while others have a clean air delivery rate (CADR) rating. The higher the filter rating, the more efficient it is. If you have allergies, you can buy a filter with a MERV 8 rating or higher. However, ensure you check the filter compatibility with your system. The more efficient a filter is, the more it overworks the system, which can be damaging.
