To achieve the maximum EMF Filtering results it is recommended that you install 1 StopWatt for every 800-1200 sq.ft of space. Using more than recommended will not increase the results.

Yes! Now that the Residential Energy Stabilization (RES) law has been passed, Power Factor devices & EMF Filters such as StopWatt are finally legal in the USA.

The results will vary depending on many factors including: Size of Home, Electricity Usage, Solar Usage, Location/Climate, Power Company, Age of Home and many others. We try not to make any claims or guarantees but we do ask all customers to give StopWatt a full 2 months to filter out the electric pollution between the range of 4 and 150kHz (which is the most dangerous dirty electricity carried by your electrical wiring). If, at the end of the 2 months, the results are not what you expected, simply contact us via Email and we’ll be glad to take the unit(s) back for a full refund. No questions asked.

Yes. That’s one of the wonderful benefits of using a Power Factor Correction device such as StopWatt. By making your home electricity flow more efficiently, you are using less power and conserving energy.

For one unit, we recommend you install it somewhere central. Most people usually use
a location close to the electrical breaker box as it’s more convenient and out of
the way. However, as long as it’s somewhat centralized you’ll be fine
For multiple units, we always recommend installing them as far away from each other
as possible. Ideally, at opposite ends of the home. This will allow you to maximize
the effect of the devices.
Placing the devices close to the circuit breaker is ok but not required. Most people
use that location simply because it’s more discreet and convenient.

Yes, all orders come with a 1- year Standard Warranty. If for any
reason your StopWatt device breaks, is damaged or stops working, simply send it back
for a new one, free of charge. Please contact us at support@stopwatts.com to report a
damaged or defective device. You can rest assured knowing you’re covered.

It’s similar to a water or air filter. StopWatt EMF Filters take time to completely filter the Dirty Electricity from your home (approximately 3-4 weeks for the average home). The moment you remove the filter the EMF dirty electricity will start to come back. So even though it is completely safe to unplug StopWatt devices, we recommend you always leave them plugged in to maximize the amount of EMF Filtering and prevent any benefits to be lost

The moment you plug in your StopWatt, the green bar will light up showing that the device is working and the dirty EMF electricity is being filtered.

No, at this time StopWatt is only compatible with 110v, North American electrical systems. We are currently developing, and hope to launch, a 220v version in the coming 6-12 months.
