I have both the humidifier and now, thanks to a Thingdrop deal, the filtered shower head. They're nicely designed products, but I don't think they make a significant impact on your well-being, but that doesn't necessarily mean they're bad.
For the humidifier, we wanted something small that would look good beside the bed. Most humidifiers are pretty ugly, so the design and the idea that Canopy had a filter and that the parts were dishwasher safe sold us on it. During a dry winter, it's a nice thing to have, and according to my air quality filter it does increase humidity a little bit. But if you look at Wirecutter reviews, they recommend units that can really make a difference in your indoor air. Canopy is pretty weak in that regard.
The filtered shower head is hard to evaluate. We live in NYC, where water quality is generally high, and we live in a new-ish building so we aren't worried about rotten pipes. I didn't really have a complaint about my water before, but I didn't like my shower head, so I figured this would be a good opportunity to replace it with something better, and filtering my shower water couldn't hurt either. It's been a few weeks now, and I appreciate the water pressure and adjustable flow patterns (which were flaws of my existing shower head). It is a fairly large unit, so you may want to measure if the pipe you connect the shower head to is low; the Canopy shower head just barely fits for us.
It's a decent-looking thing, but we're renters anyway, so none of our fixtures are particularly note worthy. The packaging was nice. I rarely notice the scent working — that seems like a gimmick. Overall, both products are nice, but neither are necessities and if you don't care about the design, there are almost certainly better-performing options on the market.
