I would suggest using a phone or system you don't usually use to browse the web to hold your coins or better still an Hardware wallet.
A phone you don't usually use to browse the internet sounds like a device that is connected to the internet sometimes, but not all the time. Mind you that such a device is not airgapped and it it is not safe for your coins, an offline set up has to be completely offline. In your case you were attacked by a clipboard malware, you can avoid that if you use your online device very well and also double check the address you want to send Bitcoin to.

I never knew this was possible so usually just copy the address and send without confirming much. Well turns out that was a big mistake on my part. Never knew that clipboard can do such. I don't know if it's a malware, I ended up using an address that wasn't mine and funny holds some units of Bitcoin.
Still confused how something like this could happen, but try to be cautious and don't feel too lazy to cross check your address before sending or posting. Recall Bitcoin transactions are irreversible after 6 confirmations, once confirmed it's gone. You can tell the wallet address it went to but not the owner. Except they are careless, which I doubt they are

Also you may have to also see the way many can loose their crypto asset from copy and paste already discussed long time ago by LoyceV from the forum here, if we don't download a malicious apps or use their links, we are not going to be affected, many got into this because they don't even got aware they are into it in the first place until they experience the scam.

)even after format and reset.Or you could just get an Airgapped device / Hardware wallet just as you've mentioned.
It is called clipboard malware. It is used by scammers to infiltrate your keyboard, it intercepts your keyboard by replacing what you copy on your keyboard and paste something different. They use it to make fraudulent cryptocurrency transactions and can also replace important informations you copy such as credit cards details, passwords etc. You can avoid them by not visiting any unsolicited links you come across and keeping your antivirus software updated to stop such softwares from been installed accidentally in your system.
The suggestion should be you should rather store your coins on a device that you have never used to browse the internet before or an hardware wallet. And it doesn’t just end there make sure to cross check your transaction details before broadcasting your transaction, you never can be too sure even on an assumed clean device
Exactly. Even dust attack and address poisoning is possible on clean devices. But the one that has been reported led to coin loss is address poisoning as the attacker make use of address similar to the victim's address. 
It is either it is a clipboard malware which I would advise you to read this thread on how not to lose your bitcoin through copy and paste or you mistakenly copy the wrong address either through a dust attack on that address.

It is better to check and recheck the address that you are sending to someone before sending the address. It is better you check and recheck the address that you are sending coins to before sending the coin.
Bitcoin transactions are irreversible after 6 confirmations, once confirmed it's gone.
After 1 confirmation, it is gone. If the transaction does not support replace-by-fee, the coin has likely gone even when it is not yet confirmed. Even if the transaction support replaced-by-fee, it is possible that it might have been too late.
