If you do just a light amount of searching almost everyone under the sun is selling the exact same bags along with usually some combination of a hand pump, battery pump, tiny/useless silica gel bags, and moisture test strips - a ton of which seem to be totally fake. Hit up Google, and you'll find the same bag and pump kits sold as sous vide bags.
The problem with the bags is the textured side. The pattern serves zero purpose other than to weaken the bags - albeit some listings try to claim it helps transfer moisture/air out which makes no sense at all (why wouldn't moisture/air come in?). I've had many of these fail on first use and finding the leak it's always a tiny hole in the textured side. If you read reviews across sellers you'll find a lot of issues with sealing.
*That all being said* if you can get a big bundle of the bags for cheap then a few failures isn't a big deal. What I do is pump them down, press the valve flat, sit them aside for a few minutes, and if they start letting air in I toss that bag, otherwise they go to storage. If they hold the first time they seem to survive quite a few uses after that.
Dear filament bag industry: The first vendor to sell a version of these that's simply got thick non-textured plastic on both sides will get my money.

Currently store my filament (only keep 5-7 rolls at a time) in a smallish sealed rubbermaid container with a a rechargeable plug in dehumidifier (Eva-Dry style). Works fine but this looks mo-better.
Reusable sous vide bags would prolly work just the same and probably cheaper if I had to guess.

Filament is susceptible to humidity and over time, if not stored in a cool, dry place will absorb moisture and cause extrusion issues including clogged nozzles. Each use case is different though, I've noticed some brands of filament are worse about this than others.
Truthfully, most people are fine storing spools in a plastic tote with some desiccant, rechargeable desiccant is really nice as well. I do this and have a filament dryer for problem filament and periodically shove a couple spools to bake in there for a while. Resolved the handful of problems I was having.
I am about a year into 3d printing and have just kept my spools in the bag they came in (unsealed) but with the big desiccant bags with them, so far, I have had no issues, but I don't print much. Even though I am in the Houston area and is very humid outside, inside humidity is not bad.
I have debated getting something like this vacuum sealer thing, but also think just large ziplocks with some desiccant packets would work for me as well.

For a split second there I was also wondering how you dry filament in a clothes dryer and how bad an idea it would be.

Nylon filament is one of the worst for absorbing, PLA is one of the best for not absorbing. TPU can be pretty bad for absorbing moisture as well, PETG is a little worse than PLA.
