Air purifiers with HEPA filters. I have three of them and I’m about to get a fourth one. I have severe seasonal allergies and so does my SO, and we live in a place that gets a lot of wildfire smoke most summers. We also use the air purifiers as white noise since we live in a densely populated area. We use all of them daily.

Vacuum Cleaners

We have four.

One lives in my backyard shed, for cleanups and dust collection.

One lives in my garage, for cleaning the cars.

Our house is split level, so we have one for upstairs and another one for downstairs. All to save carrying it up and down the six steps that divide the front and back of the house. These two are the same make and model.

One broom for each room.

Children

Hand lotion, lip balm.

I buy my hair gel in liters when the price goes low enough, not when I need it, so have two or three liters sometimes.

Two dogs and two cats because people left them with us. I’d be good with one cat.

10mm wrenches. Saw a deal online years ago for 20 wrenches for like 20 bucks. I was still doing field work at the the time so 10 and 11 mm were common purchases for me. They didn’t break, so there was no need for an expensive warranty. They just got misplaced, usually by a trainee who didnt have their own tools.

It was frustrating because buy even one cheap wrench was $10, but a kit of 8 or 10 wrenches could be bought on sale for $20. I have a few of those kits too, and a few socket kits. I have yet to use most of the pieces in 20 years. I mostlt just needed the 10, 11, and 13mm.

A 20 pack of 10mm for cheap? I couldn’t pass that up. Then I stopped working field. Now I have a shed full of tools that I might never use again. Nothing wrong with them except some old batteries maybe. I refuse to get rid of them in case I have to back to field work. But it makes me look like a hoarder.

Double edge safety razors: if I had to choose only one, Rockwell 6S is enough, but they really perform different and have different feel. I mostly use four or five on a daily basis, but it is more than necessary.

Also, fountain pens: it’s pretty much the same, TWSBI pen(s) would suffice, but there are too many brands and models with different look and feel, hard to choose only one. Plus in case of pens multiple ones allow for use of different inks at the same time (those I also have multiple compared to the amount that would suffice, even in the same colour)

After thinking about this a bit and reading through this thread, I realized I might have a problem about always wanting spare things. I have more than one of a lot of things - lip balm, battery banks, phone & watch charging docks, dogs, headphones and earbuds (even two of the same kind), computers, pillows (I have spares of my main and body pillows), and the list goes on. I apparently need to re-evaluate my habits.

Headphones. I have my commuting headphones, walking headphones, working headphones, video game headphones, music headphones… I also have two pairs of earphones.

I could get down to two pairs of headphones and one pair of earphones.

Keyboards. Wired, wireless, red switch, blue switch, LED, plain, full, half. I like having options.

I needed a machete one time and honestly could have managed with a different tool. I now own three of them.

Games I’ve got through steam or gog, but still pick up if it’s free on Epic.
