How often should I replace this Paper Frame Pre-Filter?
Usually, we recommend checking it every 1 to 3 months. If the filter looks very dark or if you notice the air flow is getting weak, it is time for a quick and easy replacement.
Will the paper frame fall apart if it gets wet?
No. The frame of this Paper Frame Pre-Filter is made of special moisture-resistant cardboard. While it is not meant to be soaked in water, it stays strong and stiff even in very humid air.
Is this Paper Frame Pre-Filter recyclable?
Yes. Since the frame is paper and the media is synthetic, this Paper Frame Pre-Filter is much easier to dispose of and recycle compared to heavy metal filters.
Can this Paper Frame Pre-Filter catch tiny bacteria or viruses?
This is a G4 level filter, meaning its main job is to catch larger dust, hair, and lint. For bacteria, this Paper Frame Pre-Filter works together with a "High-Efficiency" (HEPA) filter which sits behind it.
Can I wash this Paper Frame Pre-Filter?
No. This Paper Frame Pre-Filter is designed to be disposable for better hygiene and performance. Because it is very low-cost, replacing it with a new one is more effective than trying to wash it.
