Our verdict on each
AquaTru
AquaTru suits households in US that want PFAS and lead reduction from tap water and can absorb $375 up front. Replacement filters then run $99.85 a year, so the steady cost after the purchase is modest even though warranty cover is only 1 year.
LARQ
LARQ suits people who want purified water straight from a bottle and will accept frequent cartridge swaps. The entry price is €58, and the cartridge ranks high on value at position 2 of 50.

Pros and cons
AquaTru
Pros
- AquaTru states that its purifiers reduce PFAS and lead, and IAPMO certification to NSF standards covers the countertop and under sink models for a contaminant list that takes in arsenic, chlorine, fluoride, nitrates, nitrites and glyphosate.
- Running costs stay modest at $99.85 a year, with replacement cartridges listed at $29.95 to $59.95.
- Cartridge life of 2,271 to 4,542 litres stretches refills out, so that annual cost covers a large volume of water.
Cons
- Entry pricing of $375 sits well above the category entry median of €179.99, so the outlay is the main barrier.
- Installation is required, so $375 covers the unit and not the work of fitting it.
- AquaTru ships to US, so buyers elsewhere have to settle delivery before choosing a model.
LARQ
Pros
- Entry price of €58 keeps the first purchase well below the water filter field, ranking 17 of 52.
- Cartridge price of €10.65 places LARQ at 2 of 50 on that measure.
- PFAS and lead reduction is a yes, which matters for anyone focused on those contaminants.
Cons
- Annual filter running cost of €63.90 ranks 10 of 46, weaker than the cartridge price suggests.
- Support runs on email and help centre only, so there is no phone line for quick troubleshooting.
- The bottle format in bottle is portable but filters one drink at a time, unlike the reverse osmosis systems from Waterdrop (EU) or Culligan Consumer Products.
Who each suits
AquaTru
Who it suits
- Households in US that want PFAS and lead reduction and can pay $375 up front.
- Drinkers who value long cartridge life, since 2,271 to 4,542 litres keeps refills infrequent.
- People choosing between formats, with AquaTru Carafe, AquaTru Classic, AquaTru Under Sink covering a carafe, a classic purifier and an under sink unit.
Who should look elsewhere
- Buyers on a tight budget: IBBL is a countertop purifier, a simpler format, and the category entry median of €179.99 sits well below AquaTru's $375.
- Shoppers after a tankless under sink menu: Culligan Consumer Products lists its Aquasential Tankless RO Drinking Water Filtration System, and Waterdrop (EU) also offers a tankless reverse osmosis system, so both reach formats beyond AquaTru Carafe, AquaTru Classic, AquaTru Under Sink.
- Renters unwilling to fit an appliance: installation is required here, whereas the countertop format suits a kitchen where plumbing work is not on the table.
LARQ
Who it suits
- Drinkers who fill a bottle on the move and want PFAS and lead claims on a certified filter
- Households in the US, Canada or the UK, where LARQ sells under LARQ, a BRITA SE company
- Buyers who prefer a one-off purchase over a filter subscription, given the €58 entry point
Who should look elsewhere
- People who filter a whole household at once, who should look at the reverse osmosis systems from Waterdrop (EU) or Culligan Consumer Products
- Buyers outside US, CA and GB who cannot find a local source
- Shoppers who want phone support, since LARQ offers email and help centre

Questions about each
AquaTru
What does an AquaTru purifier cost to buy?+
Entry pricing is $375 for an AquaTru purifier, paid at purchase rather than renewed on a schedule. The range runs across AquaTru Carafe, AquaTru Classic, AquaTru Under Sink, so that figure reads differently depending on whether you pick a countertop or under sink model. Budget for filters separately, because they are the part you replace.
How much do AquaTru replacement filters cost over the year?+
Cartridges list at $29.95 to $59.95, and the annual filter cost is $99.85. Those two figures make up the renewal side of ownership, since the machine itself is bought at purchase. A household that drinks and cooks heavily on filtered water reaches each cartridge change sooner than a lighter one does.
LARQ
How much does a LARQ bottle cost to buy?+
The LARQ Bottle Filtered Flip Top starts at €58. That entry price ranks 17 of 52 across the water filters we compare, so the initial outlay sits toward the lower end of the field. There is no subscription tier in the range, so nothing renews automatically.
What does a replacement filter cost?+
A plant-based bottle filter cartridge costs €10.65. On price alone that ranks 2 of 50, among the better cartridge prices in the group. The cartridge is the only consumable the bottle needs, so this figure sets the running cost.
