1. Brita Water Filters
Brita has been a household name since 1966 and continues to lead the Irish market with its trusted water filtration products. In 2026, Brita offers thirteen different water filter pitcher models, designed to fit a range of needs from single users to large families. Their Longlast+ filter is a game-changer — it lasts up to six months, which is about triple the lifespan of Brita's standard filters. This means fewer replacements and less hassle.
These filters are tested and certified to remove up to 99% of lead, cyanide, cadmium, copper, and mercury, which are common contaminants in some Irish water supplies. They also significantly reduce chlorine taste and odour, improving water flavour for everyday drinking and cooking. Brita pitchers come in various sizes, from small 1.4-litre models perfect for individual use to larger 3.5-litre options for families.
One thing to note is that while the Longlast+ filters last six months, the standard Brita filters only last about two months, so it’s important to pick the right filter for your needs. Availability across Ireland is excellent — you can find Brita products in supermarkets like Tesco, Dunnes Stores, and online retailers such as Amazon Ireland.
Pros: Wide variety of pitcher sizes and styles, long-lasting Longlast+ filters reduce replacement frequency, effective contaminant removal including heavy metals, readily available in stores and online, simple to use and maintain.
Cons: Standard filters have shorter lifespan (2 months), some premium models can be pricey, no direct tap filter options from Brita.
Best for: Families or individuals wanting flexible pitcher options with reliable filtration and long filter life, plus easy access to replacement filters.
Pricing: Brita pitchers range from approximately €20 for smaller pitchers like the Marella 1.4L up to €50 for premium models like the Elemaris XL 3.5L. Replacement Longlast+ filters cost between €25 and €30 for a pack of three, lasting up to 6 months each. Standard replacement filters are cheaper, around €15 per pack but need more frequent changes.
2. ZeroWater Water Filters
ZeroWater offers a more premium filtration experience with fewer product options but very strong results. Their pitchers are designed to remove nearly all total dissolved solids (TDS) from tap water — this includes minerals, salts, metals, and even some organic compounds. ZeroWater is certified to remove PFAS chemicals, a growing concern in Ireland and worldwide due to their persistence in water supplies.
The pitchers use a unique five-stage filter system, which is more complex than typical carbon filters. This system breaks down contaminants more thoroughly, and ZeroWater includes a digital TDS meter with each unit so you can test your water before and after filtration. This gives peace of mind, showing exactly when you need to replace the filter. The filter lifespan ranges from about 20 to 40 gallons (roughly 75 to 150 litres), depending on water quality.
ZeroWater pitchers come in sizes from 1.5 litres up to 3.8 litres, suitable for individual or family use. The design focuses on premium build quality with a sleek look that fits modern kitchens. While their filters cost more than Brita’s, the depth of filtration is superior, particularly if your water supply has higher levels of dissolved solids or contaminants.
Pros: Removes nearly all dissolved solids including PFAS, includes TDS meter for easy monitoring, five-stage filtration provides thorough purification, stylish design, good customer reviews in Ireland.
Cons: Higher price point with pitchers costing €40-€70, filter replacements are more frequent (every 20-40 gallons), fewer product choices than Brita.
Best for: Health-conscious consumers wanting the cleanest water possible, people with concerns about dissolved solids or PFAS contamination.
Pricing: ZeroWater pitchers range from about €40 for smaller models up to €70 for larger capacity pitchers. Replacement filters cost around €30-€35 each, typically lasting between 20-40 gallons depending on water quality.
3. Tap Filters (Various Brands)
Tap filters offer a different approach — instead of pitcher-based filtration, these install directly onto your kitchen tap to provide filtered water on demand. This means constant access to filtered water without the need to fill and refrigerate pitchers. Tap filters are popular in Irish homes where space is tight or convenience is a priority.
Brands available in Ireland include Brita’s On Tap filter, Culligan, and Water2Buy among others. Prices vary widely depending on features and build quality, ranging from around €50 for basic models up to €150 for more advanced systems with multiple filtration stages. Some tap filters reduce chlorine, lead, heavy metals, and even bacteria, though effectiveness varies by brand.
Filter cartridges typically require replacement every 2-3 months, depending on water usage and quality. Installation is usually simple and requires no special tools, making them a DIY-friendly option. However, some tap filters may not fit all tap designs common in Ireland, so checking compatibility before purchase is important.
Pros: Continuous filtered water on demand, space-saving with no need for pitchers, easy installation, wide price range with options for different budgets.
Cons: Filter replacements needed every 2-3 months, may not fit all tap types, potentially less thorough filtration compared to premium pitchers like ZeroWater.
Best for: Busy households wanting instant filtered water without pitcher refills, apartments or small kitchens where counter space is limited.
Pricing: Tap filter units range from about €50 for basic models to €150 for advanced multi-stage filters. Replacement cartridges cost between €15 and €40 depending on brand and filtration level, with typical replacement intervals every 2-3 months.
When choosing the best water filter in Ireland for 2026, it really comes down to your priorities. If you want a broad selection of pitchers with long-lasting filters and solid contaminant removal, Brita is a reliable choice, especially for families. ZeroWater stands out if your focus is on premium filtration that removes nearly all dissolved solids including PFAS, with the added benefit of a TDS meter to monitor water quality. Tap filters suit those who want filtered water straight from the tap without the fuss of pitchers but may require more frequent filter changes and careful tap compatibility checks. Weigh your budget, water quality concerns, and lifestyle to find the filter that fits you best.
