How large is Pure Skies?
During installation, Devic Earth’s technician(s) will:
After installation, a member of our team will contact you to:
During week 1, baseline measurements of air quality at your location (with Pure Skies off) will take place. A baseline air quality report will be sent to you.
Once a stable baseline is established, Pure Skies will be powered on remotely. Air quality will start to improve in 2-4 days for outdoors, and sooner for indoor installations. Periodic reports will be sent to you at the end of week 2-3, then monthly thereafter.
During subsequent weeks, air quality will progressively improve, reaching a maximum benefit after 8 weeks (assuming no change in season).
No. The safety profile of Pure Skies is similar to Wi-Fi.
Pure Skies will not affect operations inside a factory, industry, office or commercial space, or home. In addition, there is no effect on industrial processes such as painting, buffing, or finishing. We have several use cases in this regard.
No. Formal laboratory testing confirms this.
Pure Skies operates on a pulsed radio wave frequency in the WI-Fi spectrum, whereas routine Wi-Fi transmits continuously. This basic difference ensures that there is no effect on performance of the Wi-Fi network.
No. The effect of Pure Skies is very size dependent – only particle pollutants (and some gases as aerosols) less than 20-30 microns in diameter. Pollen, pet dander, dust mites, cockroach excreta (yuck), and other common airborne allergens are usually larger than this (or have components that are larger than this) and are therefore not cleared by Pure Skies.
If your concern is allergens due to asthma, you’re best bet is: 1) Minimize exposure to triggers; and 2) Get a HEPA based air purifier for your home and/or office.
No. Pure Skies works by using pulsed radio waves in the Wi-Fi spectrum to create a weak electromagnetic field. This causes the positive and negative charges that are present in particle pollutants to shift slightly (dielectric effect) so that, like little magnets, they move a bit faster, collide, and settle out of the atmosphere onto the ground.
Clean rooms require complete removal of dust and other particles. A HEPA based filtration system, often combined with an ESP, is the best choice here.
Generally, no. While it’s true that some odour causing amines and other smelly compounds adhere to PM2.5 and can be cleared with Pure Skies, there are just too many chemical compounds that cause odour for us to make a reliable claim.
No. We get this question all the time! (Think dengue) But no. Use mosquito repellents with DEET, install plug in chemical mosquito repellents, wear long pants and full sleeve shirts during dawn and dusk, and remove stagnant water sources around your home or office where mosquitoes breed.
We have not observed resuspension of dust both in the lab and in field settings. This is likely due to the limitation of our pulsed radio wave technology on particles < 20-30 microns in size, rather than visible (larger) dust which is easily re-suspended by wind or vehicle traffic and scattered into smaller subcomponents.
No. Pure Skies is tested and certified to meet national and international standards for products which use radiofrequency energy (including Wi-Fi) for non-telecommunication purposes (e.g. like an MRI scanner).
Prior to commercial release, Pure Skies was extensively tested for safety by Devic Earth’s co-founder, Dr. Srikanth Sola, and his team at a large tertiary care hospital from 2008-2018. No adverse effects have been found in infants, children, adults, certain animals (rock bees, migratory birds, fruit bats, and others), water quality in water bodies or bore wells, agricultural output, landscaping, bacteria, or fungi.
A. Pure Skies works by accelerating dry deposition. In nature, these particles agglomerate and settle out of the atmosphere onto the ground or on vegetation. There is no visible dust or layer of pollutants because: 1) Pure Skies affects only microscopic (not visible to the naked eye) pollutants; and 2) These pollutants are present in the parts per million or sometimes parts per billion concentration – too few to be visible.
Pure Skies is not designed, manufactured, or intended for use in:
Devic Earth Pvt. Ltd. specifically disclaims any liabilities or warranties for any use of the product by purchaser for dangerous applications.
In the event that a hazardous or critical event were to occur in a location where Pure Skies is installed, we will remotely turn off the Pure Skies unit until the situation has been stabilized.
For purposes of depreciation, the air pollution equipment is rated to last 4-5 years with routine maintenance. Longevity of the core technology is 10+ years, based on actual testing since 2008.
Depreciation is 20% per year based on a lifetime of 5 years and a classification as Plant & Machinery.
The subscription plan is like a lease, except that all maintenance and spares are included (i.e. a comprehensive maintenance plan). The equipment is owned by Devic Earth, and depreciation cannot be taken. Devic Earth takes the responsibility of equipment maintenance.
AMC ranges from 12% per year for smaller indoor units and up to 15% per year for large indoor or the outdoor units.
