I love the idea specially in a time where faucet water is not as clean and at the same time we need to reduce plastic consumption.
But I spend more time trying to clear the filter from water bubbles than actually filling or serving water. Is really annoying. I already threw away 3 filters because no matter how many times I removed them or banged on them the bubbles wouldn't come and the water won't drain from the top. 
As much as I would like to keep using it is passing the limits of my patience and budget.
