Changing an air filter is a simple task that can have a big impact on the air quality in your home. To ensure you get the best fit for your unit, it's important to measure accurately and choose the right size. Our guide will help you do just that. When it comes to air filters, size is paramount.
The most widely used system for measuring filter efficiency is the Minimum Efficiency Reporting Value (MERV) classification system. This rating indicates the filter's ability to capture particles of different sizes, from pollen and dust to smoke and mold spores. A 20x25x1 Merv 13 air filter and a 20x25x4 MERV 13 oven filter will have the same filtration performance. In apartments, shared ventilation systems can cause harmful particles to recirculate throughout the building, so it's important to change your air filter regularly. To make sure you get the right size, double check the product description before placing your order.
If you're still unsure, it's best to check all the numbers before opening the factory packaging. When it comes to selecting a filter, you don't necessarily need to pay more for a better one. However, if cleaner air is a priority for you, medium-efficiency MERV filters like the Nordic Pure MERV 12 can significantly reduce airborne dust, mold spores, pollen, and even smoke. This can help alleviate respiratory conditions, according to an NIH review. The Home Depot also offers a full range of air filter accessories, making it easy to keep your system running at peak performance. So follow our guide and learn how to change an air filter today!.
