Looking to buy Brita Water Filters?

With over 50 years in business, the makers behind BRITA replacement filters know a thing or two about improving the quality of drinking water from your tap. So, say no to single-use plastic bottles and enjoy crystal clear, refreshing water with OnBuy's range of replacement filter cartridges.

How can BRITA help me become more environmentally friendly?

To start with, a BRITA replacement filter works hand in hand with your choice of BRITA jug, carafe, bottle or tap filter system. By opting for fresh water delivered straight to your drinking glass instead of purchasing bottled water from the shop, you're not only minimising your use of single-use plastic but reducing your carbon footprint, too!

Each BRITA replacement filter has a generous life that delivers approximately four weeks of water filtration with each filter. If you stick to the recommended water intake of six to eight glasses a day, this can save over a whopping 17 plastic bottles (2-litre capacity) a month on average. At the same time, it also cuts your car journeys to the shop - because let's face it, bottles of water are not exactly the lightest of supplies to carry!

When it comes to disposing of your BRITA filters, you'll be pleased to hear that the company developed a brilliant recycling programme back in 1992, meaning all parts of BRITA filter cartridges have had the ability to be fully reprocessed for the recycling of materials since the programme's launch. You can find in-store recycling schemes conveniently across the high street, with a total of over 7000 recycling locations in the UK.

What BRITA replacement filters are there?

For great tasting water without the need for bottled water from the shop, a BRITA replacement filter or BRITA cartridge is your go-to. These filters are cleverly designed to reduce limescale, chlorine and more, leaving you with water that's safe to consume and ultra-convenient to have on hand.

If you're the owner of a classic BRITA jug, the BRITA CLASSIC filters will help you make the most of your nifty kitchen appliance. Easy to fit and replace, they feature 4-step filtration to help rid your water of any unsavoury substances.

First, your water flows through a fine mesh filter that works as an intensive pre-filtration method, before making its way to the ion exchange resin responsible for limiting limescale and metals such as lead and copper. Activated carbon filtration then reduces any substances that affect the smell and taste of your water (for example, chlorine!) and finally, a special fine mesh filter retains any particle mixture.

Meanwhile, BRITA MAXTRA and MAXTRA+ filters are suitable for use with an array of jugs, including the BRITA Fun, BRITA Style and BRITA Marella ranges, to name a few. In addition to providing water filtration at home, BRITA MAXTRA and MAXTRA+ filters are ideal for use in the office with the larger BRITA Flow filter that stores a generous 8.2 litres of water!

Built to slot comfortably in your BRITA water bottle, MicroDisc filters have a completely different design to the BRITA replacement filter you'd use with your jug. These nifty little discs have just as much power to remove any nasties to help you stay refreshed and hydrated on the go!

If you're after a BRITA cartridge for your filter tap, you want to look out for the P 1000 and P 3000 filters that are designed for serious water consumption: 1200 litres and 3000 litres a year respectively. Ideal for larger households and organisations, you'll have fresh, delicious water straight from the kitchen tap. 

So, with a plethora of BRITA filters and cartridges to pick from, you'll get to enjoy not only better tasting water, but delicious teas, coffees and hot drinks without any chemicals that could affect the taste of your favourite beverage - all while never having to resort to bottled water again!
