There aren't so many clean faucets. Mostly of faucets are filled with popups, url shorteners, hidden coinhive miner and etc. And if faucet is clean, they are paying lower rewards, because they get less revenue from advertisemnts that they are using. I selected several clean faucets, you can try it:
Vipfaucet.ga, Btcsmile.com, Starbits.io, Forumcoin.win/btc, Xfaucet.net, Konstantinova.net, Fautsy.com, Coinue.com/faucet.
You also can check my Faucethub faucet list, maybe you will find some more good faucets;) :
