Revised Content: The Importance of MERV Ratings and Filter Thickness

MERV, or Minimum Efficiency Reporting Value, is an industry-standard used to measure the effectiveness of air filters. While this technical term may be challenging for some consumers to grasp, we have developed an intuitive, application-based naming system to help you easily identify the filter that best suits your needs.

Indoor air quality can be significantly impacted by factors such as pets, odors, and smoking. OlitAir Air Filters offers a wide range of air filters to help you breathe easier and ensure your indoor air is clean and fresh.

Proper filter fit is crucial for the optimal performance of your HVAC system. When selecting a filter, it's important to consider not only the length and width, but also the thickness. Most standard air filters are typically 1-2 inches thick, while media filters generally range from 3-5 inches. To determine the correct size for your system, we recommend using a measuring tape to measure the dimensions of your current filter, which are often printed on the frame.

Understanding the Differences: Nominal Size vs. Actual Size The nominal size is a rounded measurement, typically displayed in a larger font (e.g., 20 x 20 x 1), while the actual size is the precise dimension, usually shown in a smaller font (e.g., 19.75 x 19.75 x 0.75). All filters have both nominal and actual size information.

Measuring Your Air Filters If the dimensions of your current air filter are not listed on the frame, use a tape measure to record the length, width, and depth, and then round up these measurements to the nearest inch to find the corresponding nominal size. This will make it easier to find a replacement filter when shopping online or in-store.

OlitAir Furnace Air Filter Features: 1. Packaging includes 1 ABS frame and 7 filter media (not 7 ABS frames). 2. The package contains 7 filter media, with 1 piece pre-set in the frame and the other 6 pieces in a zipper bag, arranged in 3 layers with 2 pieces per layer. These pieces need to be separated when used. 3. The ABS outer frame is sturdy and non-deformable, making filter media replacement easy. 4. High efficiency and low resistance: The filter media is made of high-efficiency, low-resistance meltblown material with an advanced hard skeleton compound, providing a larger filter area to capture more particles while allowing more air to pass through. 5. We offer a 3-year warranty on the ABS frame and promise to replace it free of charge for any non-human-related damage.
