Wire Frame Filters For Fan Coil & Heat Pump Units
Home Trade Standards provides full delivery services for all Wire Frame Filters, Across GTA & Toronto Area.
Wire Frame filters are disposable made of fibreglass They have a MERV rating of 1 to 4. Typically, you should be able to hold these filters and see through them. If they are dirty, you should be able to detect it is time to replace them.
What is Merv Rating:
MERV stands for “Minimum Efficiency Reporting Value”. MERV rating on an air filter describes its efficiency as a means of reducing particles of 0.3 to 10 microns. The higher the “MERV” rating means higher filtration efficiency or simply the better it is at trapping particles within that size range. These ratings indicate a filter’s ability and performance to capture larger particles between 0.3 and 10 microns (µm). The data of the table below is derived from a test method developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE). The higher the MERV rating the better the filter is at trapping specific types of particles.
| MERV Rating | Average Particle Size Efficiency in Microns |
|---|---|
| 1-4 | 3.0 – 10.0 less than 20% |
| 6 | 3.0 – 10.0 49.9% |
| 8 | 3.0 – 10.0 84.9% |
| 10 | 1.0 – 3.0 50% – 64.9%, 3.0 – 10.0 85% or greater |
| 12 | 1.0 – 3.0 80% – 89.9%, 3.0 – 10.0 90% or greater |
| 14 | 0.3 – 1.0 75% – 84%, 1.0 – 3.0 90% or greater |
| 16 | 0.3 – 1.0 75% or greater |
