Types of 16x20x4 Furnace Filters
When selecting a 16x20x4 furnace filter, understanding the types available is crucial. Below are the most common types:
1. Fiberglass Filters
Fiberglass filters are the most basic type. They are inexpensive but typically have a low MERV rating (usually 1-4). This means they capture larger particles but are not very effective against allergens.
2. Pleated Filters
Pleated filters are designed with a larger surface area, which increases their ability to capture dust, pollen, and other allergens. They come in various MERV ratings, typically ranging from 8 to 13, making them a popular choice for residential use. Brands like Filtrete and Honeywell offer high-quality pleated options available at retailers like www.lowes.com.
3. HEPA Filters
High-Efficiency Particulate Air (HEPA) filters are designed to capture 99.97% of particles that are 0.3 microns in size. These filters are excellent for people with allergies or respiratory issues. However, they may require modifications to your HVAC system due to their density and airflow restrictions.
4. Washable Filters
These filters can be cleaned and reused, making them an eco-friendly option. While they have a higher initial cost, they often save money in the long run. Brands like cycleairfilters.com specialize in washable filters, which are gaining popularity among environmentally conscious consumers.
Applications of 16x20x4 Furnace Filters
The application of a 16x20x4 furnace filter varies depending on its MERV rating and type. Here’s how you can choose the right filter based on your needs:
1. Residential Use
For most homes, a MERV rating between 8 and 13 is recommended. This range effectively captures allergens without restricting airflow significantly. Brands like filterbuy.com and www.lowes.com offer a variety of options suited for residential settings.
2. Allergy Relief
If you or your family members suffer from allergies, consider using a MERV 12 or 13 filter. These filters can capture smaller particles, including pet dander and pollen. Honeywell’s CF200A1620 is an excellent choice for those who need ultra-efficient air cleaning.
3. Commercial Use
In light commercial settings, filters with a higher MERV rating (13 and above) are often required to maintain air quality. These filters are effective in environments like clinics and offices. Retailers like filterking.com provide options tailored to commercial needs.
4. Budget Considerations
If cost is a concern, MERV 8 filters can provide a good balance of performance and affordability. These filters are often available in bulk packs at retailers like www.walmart.com, making them a budget-friendly choice for homeowners.
