I started using Waterdrop when I wanted a better (and cheaper) alternative to buying bottled water every week. I decided to invest in one of their under-sink filter systems and was surprised by how easy it was to install! Plus, I’ve already saved a surprising amount by not constantly topping up on bottled water.

I also signed up for their newsletter and grabbed a Waterdrop discount code for 10% off my first order. Then I set up a subscription for the replacement filters so I didn’t have to remember to reorder.

They often have sales around seasonal periods, too. I picked up a spare water filter jug for nearly 30% less in the January sale. And with free delivery on top, it was such a bonus. It’s one of those brands that helps you save money and waste at the same time, which I love.

Get Free Delivery on Every Order

You don’t have to spend extra to get your order delivered, which is a great bonus if you’re stocking up!

• All UK orders come with free standard delivery - no minimum spend required.
• Orders usually arrive within 2-8 business days, so there’s no long wait either.
• There’s also tracked delivery available for peace of mind.

Sign up for Offers

If you're planning your first order or want to hear about future sales, signing up for the newsletter is a must.

• You'll usually get a 5 or 10% welcome discount to use on your first orders!
• You will also get early access to upcoming sales and exclusive online-only deals.
• I signed up last year and used the code on my first under-sink filter bundle, which saved me over £15, so it’s always worth signing up.

Shop the Flash Sales & Limited-Time Deals

Waterdrop often runs great sales, you need to keep an eye out for!

• Look out for the blue banner at the top of their homepage, as this is where flash sales and time-limited codes appear first.
• I once grabbed a spare filter jug for 25% off just by checking the banner during a weekend sale.
• Their deals usually last a few days, but you need to move quickly if you see a good one.

Take Advantage of the Loyalty Programme

If you’re a regular shopper, their rewards scheme is worth signing up for.

• Create an account and start collecting points every time you shop.
• You can earn rewards by placing orders, leaving reviews or referring friends.
• Points can be exchanged for discount vouchers, for example, 1,000 points = £2 off your next order.
• I’ve managed to save £10 in points over two orders without even trying.

Use the Filter Tools to Stay on Budget

This is a quick and easy way to avoid overspending when browsing.

• When you’re shopping, use the price filter on the product pages to only see items within your budget.
• You can also filter by type, certification, brand and more, which is super helpful when you're shopping for something specific.
• This helped me stick to a set budget when buying filters for both my kitchen tap and fridge.

Refer a Friend & Both Save 20%

If you love Waterdrop, it’s worth sharing that love with others, as you can benefit from it too.

• Use your referral link to send a friend 20% off their first order.
• Once they make a purchase, you’ll get 20% off your next one too.
• I did this with my sister, and we both saved on our next filter subscription orders!

When I first started looking into water filtration, I had no idea where to begin. Waterdrop’s bestseller section was a lifesaver. It pulls together the products people trust most, whether you’re upgrading your kitchen setup or just want better-tasting tap water.

One of the first things I bought was the Waterdrop G3P800 under-sink filter. It’s one of their most popular systems, and while it’s an investment, I managed to grab mine during a sale and used a Waterdrop discount code from NetVoucherCodes for an extra 10% off. Altogether, I saved around £60. It’s been running smoothly ever since, and I love that it tells me when the filter needs changing!

If you're not ready for something quite so big, the Waterdrop Pitcher is another bestseller worth a look. The replacement filters are cheaper in multipacks, and if you subscribe, you can save 10% each time they ship, which is one less thing to remember, and cheaper than grabbing them on Amazon each time.

The fridge filters are big sellers, too. They’ve got options compatible with brands like Samsung and LG, and they’re often on offer when you buy more than one. I stocked up on a 3-pack and saved about 20% compared to buying them one at a time.

One thing I’ve noticed is that Waterdrop regularly rotates deals on these popular items, especially in the ‘Hot Sale’ section. It’s worth keeping an eye on the top banner of their homepage or signing up for the newsletter, that’s how I found out about a flash sale on Blade filters last time.

Whatever you go for, most of their bestsellers come with free delivery, which is another little saving to factor in. Plus, I’ve found the quality to be spot on! Everything is well-made, and I’ve never had to chase an order or send anything back.

If you’re just getting started, the best sellers section is the easiest place to begin. I’ve used several of them myself, and with a bit of timing and the right Waterdrop discount code, you can save a big chunk off the price, too.
