Costs Comparison for Two Years of Protection (Is ITHAS mask too expensive?)
|Disposable Mask||Cloth Mask||Sterviral ITHAS|
The details are as the following:
· Using disposable face masks, one per day, then in two whole years, you need 365x2 = 730 masks. If you spend $0.2 in buying each mask, your total cost will be $146 for two years; and all the masks are going to pollute our earth.
· Using regular reusable cloth face masks, replace one filter and one reusable cloth mask per day, you only need to buy 7 cloth masks; you wash all 7 replaced masks at weekend, and if the cloth mask can survive 50 washes, then in two whole years, you are going to need 730/7/50*7=15 cloth face masks and 730 pieces of filter. If you spend $25 in buying each mask and $0.05 for each filter, your total cost is $412 for two years.
· Using our ITHAS electrically heated face masks, you change one face cover every day, wash the entire mask every 3 weeks, and if the ITHAS mask can survive 50 washes, then in two whole years, only 52*2/3/50=1 one ITHAS face mask is needed. Your total cost is just $135 for two years.
Conclusion: SterviralTM Mask is the cheapest solution at the cost level similar to disposable face masks but with stronger protection!
