|For every $1 a hospital spends on air filters it spends $6 in elecrricity to push dirty air through those fukters.Is this delivering value? Not to mention the risk taken when the air filters don't deliver clean air and aren't operating within compliance guidelines.|
Low-cost filters can quickly lose their particle efficiency which menas they operate most of their lifetime outside of compliance guidelines.With high quality air filter you get guaranteed benefits not aviailable from any other supplier;
Nebative pressure rooms
For clean room of 10 thousands and 100 thousands level , better adopt Sub high efficiency air filter
Most cases in hospital mainly purificate microorganisms,such as bacteria, viruses,they cannot exist along must be attached to the suspended particles, forming a living biological particles, it's diameter >1umm. so use sub efficiency HEPA filter(H10-H12), which can noe only guarantee the sterilization of clean air supply, but also the cost and operationg expenses can be greatly reduced.
For the air conditioning system in hospital, higher air filtration requirements should also be demonded. Hospital air conditioning should be at least two stages of filtration and the efficiency of the second level filter must be above medium efficiency(H5-H9). In addition, reinforce the the fresh air filtration is an effective means to reduce the pollution of air conditoning system and improve indoor air quality. The fresh air filter should be filtered at least through medium or high efficiency air filters.
All the diffuser used should not be wooden in case of germ. in order to maintain the purification capacity of the air supply,they don't become to sources of the pollotion.
The sterilization requirements of ward are high, and these sanitizer drags have a strong corrosiveness to metal and rubler. These factoer should be taken into account in selecting the return air inlet, filter and damping layer.
