I've seen the following perlator and similars (also plastic ones) on some shopping sites. They claim it can decrease water consumption up to 40%. Is it possible? Is it worth to try?

    If you are filling a pot, or your sink, it will take the same amount of water anyway. It will reduce the amount of water you use when washing your hands, or rinsing dishes. Sep 15 '10 at 14:13

I've had a couple of these over the years and found that their biggest benefit was the ability to convert to a spray for better rinsing of dishes if your sink doesn't have a separate sprayer, not so much their water-saving ability. Even though a 40% reduction sounds like a lot, your kitchen sink doesn't use that much water to begin with compared to, say, your shower or clothes washer. So reducing your kitchen sink usage by 40% may not produce noticeable results on your water bill.

  • I'd echo what Mike said. We have one like this, mainly because we don't have a spray head. This is a cheap and simple way to add a spray head. That it may save some water is a bonus.
