Why is the cylindrical air filter a multi-layer high-efficiency air filter?

Pool Filter Cartridges, suitable for the use of air purifiers and fresh air system equipment of various structures in the future. This cylindrical air filter consists of a multi-layer structure from the outside to the inside, and each layer has different effects. It is generally suitable for air purification equipment with air intake from below and air out from above. Buyers who need customized cylindrical air filters can learn about:
1. The outside is covered with metal mesh. Since the frame of the cylindrical filter is only covered at the upper and lower ends, this metal mesh structure is used to prevent the filter from being damaged. Of course, the resistance structure is also taken into account. If metal mesh is not used, special attention should be paid to transportation.
2. The second layer from the outside to the inside is generally a pre-filter layer, which can filter out some large particles in the HEPA high-efficiency filter and reduce the burden of the HEPA filter. Considering the resistance structure, it is also possible not to
3. The third layer is the HEPA filter screen, which is pleated to expand the expansion area of ​​the filter paper and increase the dust holding capacity of the HEPA layer. relatively prolong its life.
4. The fourth layer is the filter layer in addition to formaldehyde and VOC. Indoor pollution is not limited to particulate matter, or smog. There are also odors, formaldehyde or organic gas volatiles. Therefore, in the fourth layer, the activated carbon filter is generally used. The general activated carbon on the market has a very general effect on formaldehyde. At this time, the activated carbon filter manufacturer needs to modify the activated carbon raw material to increase its filtration efficiency.

Feature
Powerful Filtering Performance- Innovative "dirt locking" technology enables the fabric to capture more pollutants than ordinary fabrics. The filter can effectively remove hair, leaves, dust, sediment, sand, etc.
It is a must-have for any above-ground swimming pool up to 2,400 gallons.
Improve Cleaning Efficiency- The filter only uses lead-free and BPA-free material end caps, and uses a 50% open free-flowing core to maximize water flow, thereby greatly reducing the time and frequency of filter cleaning.
Long Lifespan-Premium pleated fabric is durable in the harshest conditions. Even with significant debris buildup, our filters are designed to maintain maximum flow rates throughout the season. Cleaning the filter is easily done by removing and washing with water. Filter service life is around 1-2 years with proper maintenance.
Keep The Water Fresh: This Type VI filter for SaluSpa is sure to keep your pure spa jet massage water clean and fresh. It apply to most massage pools.
