The Venta-Sonic VS 205 ultrasonic humidifier provides your choice of cool or warm mist humidification. The demineralization cartridge uses nano-silver technology to provide microbial protection while reducing lime scale and white mineral dust.
Designed for rooms up to 600 sq. ft., additional features of the Venta-Sonic VS 205 ultrasonic humidifier include automatic shutoff when the desired humidity is reached, ultra-quiet operation and a one-year warranty.
The ProTeam Sierra backpack vacuum cleaner with commercial electric power nozzle has earned the Carpet and Rug Institute’s Gold Certification under its enhanced Green Label/Seal of Approval vacuums program.
The CRI’s new Seal of Approval/Green Label vacuum program is tiered. Bronze level requires a 10% improvement of cleaning performance over the existing Green Label program. Gold level additionally requires the machine to meet a higher dust containment standard of no more than 35 micrograms of dust particle emission. The previous CRI Green Label standard allowed for 100 micrograms.
To earn the CRI Seal of Approval/Green Label certification Gold level certification, the ProTeam Sierra backpack vacuum cleaner had to pass all three of the following independent laboratory tests:
Soil removal – using NASA-enhanced x-ray fluorescence technology to measure the precise amount of soil removed from carpet To pass, the vacuum must remove either 30 oz/sy commercial cut pile carpet or 30 oz/sy loop pile carpet.
Dust containment – this measures the ability of the vacuum to keep dirt in and not let it escape into the air you breathe. This test requires more than 100 micrograms of dust particles per cubic meter of air can escape from the vacuum.
Carpet texture retention – The vacuum must not result in more than a one-step change in the texture of the carpet based on a year of normal vacuum use
When you see a vacuum cleaner or air purifier with a HEPA designation, that should mean that it has a HEPA filter that removes 99.97% of all particles as small as 0.3 microns in size from the air that passes through it.
But sometimes you’ll see machines with HEPA filtration that filters particles down to 0.3 microns.
There is a difference between the two, and it’s an important one.
“Down to” means that if all the particles being filtered were 0.3 microns – and no larger – the filter will trap 99.97% of them.
“As small as” means that 99.97% of all the particles going through the filter will be trapped, whether they are 0.3 inches or 0.3 microns in size. But that also means that some of the particles as small as 0.3 microns, as well as some of the larger ones, will get through the filter to air you breathe.
Something to keep in mind when you compare air purifiers.
