BLUE AHEAD Aquatabs 8.5mg Review: 100 Tablets, £11.49, and One Big Reason UK Campers Keep Reordering

The Headline Finding: These Are The Tablets That Do Not Taste Of A Swimming Pool

If you have used purification tablets before, you already know the thing people moan about. Chlorine aftertaste. That tang of pool water that makes you grateful you packed squash.

The biggest single pattern across the 87 reviews I read is that Aquatabs 8.5mg mostly do not have that problem. John, who trekked Nepal for three weeks, wrote that he was "really impressed that there was absolutely no after taste in the treated water." Hugh Jones called them "very effective with virtually no chlorine after-taste." Margaret Urwin wrote "Works well, with no aftertaste." Antiproton fills a 1 litre bottle with hotel tap water, drops one in, goes out for dinner and comes back to "no bad bleach taste."

That is not universal. Jono rated them two stars and said drinking treated water was "like drinking a swimming pool." Chris Crem noticed "a slight taste when mix with 5litres tap water," and PatM's workaround is simple: "does the job, rinse thoroughly otherwise you will get a taste of bleach." Rob Lawford, writing from Everest Base Camp, admitted the flavour "isn't exactly a go to" but added his own squash afterwards and stayed healthy the whole trip.

The pattern is clear. For 1 litre doses at the correct ratio, most users taste nothing. Push the dosing, undershoot the 30 minute wait, or rinse the bottle badly and the chlorine starts to show. At this price I think that is a reasonable trade-off, and the active ingredient doing the work is NaDCC (Sodium Dichloroisocyanurate), the same EPA-approved molecule NGOs use in the field.

For Expedition And International Travel: The Reviews Read Like A Travel Diary

Scroll the 87 reviews and you get a surprisingly cosmopolitan set of trips. Ian McKimmie relied on them for a two-week trek "where all the water needed purified" and reports he "didn't reach for the imodium once." Bonza used them for a trip to Yemen and found them "tasteless, so water still tastes fine." A Kindle Customer took them to "the jungle on a trek" and paired them with a filter, exactly the belt-and-braces setup I would recommend for anywhere tropical. Laura used them for two weeks in Morocco and says she never got sick. Rob Lawford took them to Everest Base Camp.

This is where BLUE AHEAD's 8.5mg pack fits best. You want something featherweight (the whole 100-pack weighs 30 grams), reliable in the cold where pump filters and Steripens can fail, and simple enough that you can dose it at 3am with a head torch between your teeth. John specifically called out that the tablets were "much simpler to use, particularly in very cold weather, which proved a problem for more technical options e.g. Steripens etc."

The kill claim on the listing is 99.9999% of bacteria, 99.99% of viruses and 99.9% of cysts including Giardia, 30 minutes after mixing. That viral reduction figure is the important bit for travel, because bacteria-focused filters alone will miss rotavirus and hepatitis in parts of the world where the water is properly rough. Tablets plug that gap.

For UK Wild Camping: A Back-Up That Costs Almost Nothing

In the UK the risk profile is different. You are not usually worried about cholera and typhoid. You are worried about Giardia from the farm upstream, Cryptosporidium from sheep grazing above your water source, and the occasional dead thing rotting in a peat bog. A decent filter handles most of it but the 1% that slips through is the 1% that wrecks your weekend.

P hancock used the 8.5mg pack for wild camping in the Lake District and Snowdonia and wrote "I couldn't taste them at all, used for wild camping in the UK and I just added the tablets to spring water. They dissolve easily, which other varieties do not always do." David Richard has a routine that I think is the correct way to use these tablets in Britain: "I use these as part of my water purification routine when wild camping. Filter 1st then pop a pill in for complete peace of mind. Never had a problem."

That is the approach. Filter first so you are not wasting a tablet on visible sediment, then dose for the pathogens your filter cannot catch. A 100-pack at £11.49 gives you 11p per tablet, or roughly 11p per litre of treated water. I have not found another purification method that comes in cheaper per litre once you factor in the fuel cost of boiling.

For Motorhomes And Caravans: Mind The Tablet Size

This is where I want to raise a caution flag, because the 8.5mg variant is not ideal for every motorhome use case.

Karen P. bought them for her motorhome and wrote "we have a motorhome and use the tablets to ensure the water is clean and free from contamination. Other products are not strong enough to deal with the volume of water so great that we have found these." She is clearly happy. But Karen is dosing one tablet per 1 to 2 litres, which for a full fresh water tank means a lot of tablets in one go.

David Simpson left a two-star review that is worth reading carefully: "I can only assume these tablets work unfortunately I can't get the correct dose into the water tank on my campervan as tablets were crushed and almost appeared as powder." His frustration is real, and it points at a real limitation. If you are doing big tank doses regularly, BLUE AHEAD sell much stronger variants. The 33mg dose 5 litres per tablet, the 67mg cover 10 litres, and the 167mg dose 20 to 25 litres each. For a 100-litre motorhome tank the larger variants are a lot less fiddly and a lot cheaper per litre.

My take: buy the 8.5mg pack for drinking bottles, day hikes, a rucksack pouch and emergency use. If you are dosing a motorhome tank, buy one of the larger variants instead. TKMid flagged this pattern himself: "Look out for different tablet sizes for large amounts of water."

For Preppers: The Home Survival Kit Reviews Tell Their Own Story

A surprising chunk of the reviews are not from campers at all. They are from preppers and people who simply like having clean water on standby at home.

Mrs Carol keeps a pack as part of her home survival kit because they are "easy to use, ready in an emergency e.g. water main burst." John Furniss said "this product is a must for preppers, as we never know when we are going to need clean water, better safe than sorry." Graham West stocks them alongside his MSR water filter "when there is danger of virus in the water." Jampac called them an "essential holiday item" for anyone unsure about the drinking water at their destination.

Andrew J received a pack with a 2030 use-by date. That is a multi-year shelf life from a sealed mylar pouch that costs less than a takeaway. If you live somewhere prone to winter flooding, boil-notices or the occasional mains burst, a 100-pack in a kitchen drawer is the kind of low-cost insurance that pays for itself the first time you need it. The listing states Aquatabs have been used for over 20 years in emergency situations in households that do not have access to safe drinking water, which tells you something about how well the NaDCC formulation keeps.

The Packaging Is Doing A Lot Of Quiet Work

I want to flag something that shows up repeatedly in the reviews and that you do not normally expect from an £11.49 product. The pouch is actually well built.

Roland Kershaw ordered three packs and wrote "I ordered 3 packs and maybe I hadn't read the description properly but they arrived next day in a fantastic waterproof enclosure. Perfect for the rucksack or anything else you are going to store/transport them in." The listing describes the packaging as a 3 to 4 layer mylar pouch, 100 to 140 microns thick, resealable via z-lock, and waterproof. Margaret Urwin praised the "good sturdy storage pouch." Fontaine said the tablets "come in a sturdy good quality case, easy to read instructions." MB called it a "neat packet, ideal for son's backpacking trip."

The reason this matters: water purification tablets are useless if they absorb moisture in your rucksack. NaDCC is effervescent, which means it reacts with water on contact, and a leaky packet is a dead packet. The z-lock mylar solves that problem in a way the cheap foil blister packs from some competitors do not.

One honest complaint worth mentioning: Bonza noted that "it's quite fiddly getting each tablet out of its packaging, could be a better design." If you have arthritis or cold fingers, that is something to know. The individual blisters inside the pouch are small.

The Vendor Thing Everybody Mentions

This is not usually the kind of thing I spend a paragraph on in a product review, but it keeps coming up and it is too consistent to ignore. BLUE AHEAD (the seller, Blue Ahead Ltd) ship most orders with a small bag of Haribo or fruit gums tucked into the packet. It is a small thing that does not cost them much, but I counted around 15 reviews that specifically mention it.

Chloe: "Came as shown in photo, package arriving quickly and came with a packet of haribos as a thank you. Would recommend. 10/10." Lewis: "Great product and value for your money even came with a surprise in the packaging for me which lifted my mood a lot." Sarah: "Really useful, take up no room at all. Thanks for haribo." Emma Young: "Even came with a little packet of haribo sweets as a thank you for purchase! Just thought that was a lovely little touch."

More importantly, the vendor actually responds when things go wrong. Brian from Brixham wrote "after Royal Mail lost my first order, Scott from Blue Ahead responded immediately with a replacement order and 24hr delivery!" Madison reported that "the seller helped with my stolen package." That kind of service is not promised anywhere in the listing, but it is the sort of thing that turns buyers into repeat customers, and it is the reason this particular brand has held the number one spot in Camping Water Purifiers on Amazon.

The Complaints, In Full

I do not want to only quote the good bits. Every product has downsides and this one has a handful.

Taste sensitivity is real for a minority. Alicia left a one-star review saying "taste horrible, still had major diarrhoea, wouldn't recommend", which is the one review that reports both flavour and efficacy problems. Jono hated the taste. Without knowing exactly how Alicia dosed and how long she waited, it is hard to say whether this is a bad batch, a dosing error, or something the tablet simply cannot fix (and for context, Giardia cysts do need the full 30 minutes of contact time to be reliably killed).

Price comes up. Natalie G wrote "they are a bit expensive and there are cheaper brands but they work." Lynne Slater's gripe is more specific: "wasn't aware of such a large VAT amount being added" at checkout, which is a checkout display issue rather than a product problem, but worth flagging if you are budgeting.

Crushed tablets on arrival is the outlier. David Simpson's pack arrived "almost appeared as powder", which points at a packaging or handling problem rather than a design flaw (the z-lock mylar should prevent this, and the dozens of other reviewers did not have the same issue). If yours turns up damaged, contact Blue Ahead Ltd directly because the pattern across the review set is that they replace bad orders without argument.

Dosing Quick Reference

Nothing worse than a review that tells you a product works without telling you how to use it. The 8.5mg variant is designed for 1 to 2 litres of water per tablet. Drop the tablet in, wait for it to fully dissolve (they are effervescent, so it is quick), and leave the treated water to sit for 30 minutes before drinking. That 30 minute wait is not optional. It is the contact time the NaDCC needs to drive cyst and virus kill rates up to the advertised 99.9% and 99.99% respectively.

If the source water is visibly murky, filter first (a coffee filter or bandana through a second bottle will do at a pinch), because tablets work better on pre-screened water and you are not wasting a tablet neutralising leaves. For peaty Scottish streams in particular I would always filter then treat, rather than relying on tablets alone.

Warning straight from the label: this is a biocide. Do not handle tablets with wet fingers, do not swallow tablets dry, and keep the pouch away from children and pets. The safety panel notes eye irritation on direct contact and toxicity to aquatic life. Use as directed, store the resealable pouch closed, and you will be fine.

Who Should And Should Not Buy The 100-Pack

Buy the 8.5mg 100-pack if you are a hiker or backpacker filling 1 litre bottles from streams or hotel taps, a UK wild camper using tablets as a second line of defence after a filter, an international traveller visiting anywhere with suspect tap water, or a prepper who wants cheap, shelf-stable insurance for 100 litres of drinking water. At £11.49 for 100 tablets, that is roughly 11p per litre of treated water. I do not know of a cleaner-per-pound figure in this category.

Do not buy this specific variant if your main use is dosing a motorhome, caravan or boat fresh water tank in 100-litre batches. You will still be stood there breaking out 50 tablets. Go straight to the 33mg (5 litres each), 67mg (10 litres each) or 167mg (20 to 25 litres each) variants that BLUE AHEAD also sell. And if you are extremely sensitive to chlorine taste, order a small pack first and test with your usual water source before committing to a stockpile.

Overall I am rating this 4.5 out of 5. It is cheaper per litre than any alternative I can find at this safety level, the packaging is better than the price suggests, the kill claims are backed by a globally recognised active ingredient, and the seller (Blue Ahead Ltd) has built a loyal base of repeat buyers through small touches like replacement orders and packet-of-Haribo freebies. The half star comes off for the fiddly individual blisters and for the minority of users who find the taste stronger than they expected at higher doses. Still the clear top pick in its category.
