There have been no runs for store bought water, no issues with the filter nor illness and it shaves off a lot of weight and reduces trash. The device is self cleaning and easy to use. Just make sure you pump it dry before storage. The refill is pricy at 100-150usd but the filter cartridge lasts a supposed 10,000 liters.
