Branch Basics sells one concentrate that you dilute into different bottles, and the sustainability case rests entirely on that dilution math working out cheaper and lighter than buying bottled cleaners. One 33.8 fl oz bottle of Concentrate, according to branchbasics.com, makes 3 all-purpose refills, 3 foaming hand-wash refills, 3 bathroom refills, 3 streak-free refills, and one laundry refill good for 64 loads. That’s the whole pitch in one number: a bottle small enough to fit in a mailer replaces a shelf of single-purpose spray bottles.

The dilution math
Branch Basics publishes its refill math on its How It Works page: one bottle of Concentrate produces 3 Foaming Wash refills at $3.71 each, 3 All-Purpose refills at $2.06 each, 3 Bathroom refills at $4.12 each, 3 Streak-Free refills at $0.49 each, and one Laundry refill covering 64 loads at $0.26 a load (Oct 2026). At the Concentrate’s one-time price of $55 for 33.8 fl oz, about $1.63 an ounce, the 1.33 oz that goes into a 16 oz all-purpose bottle costs about $2.16, and laundry works out to about $0.27 a load (10.66 oz over 64 loads), a little more than Branch Basics’ figures. Those per-refill prices vary because each spray dilutes the concentrate at a different ratio, streak-free glass cleaner uses far less concentrate per bottle than bathroom cleaner does, which is also why a “premium price upfront” complaint about this brand is really a complaint about the starter kit, not the ongoing cost. Once the kit is bought, refilling from concentrate is cheap.
The Concentrate and Oxygen Boost bundle is $75 at branchbasics.com; the Home Essentials Kit (plastic bottles) is $69; the Ultimate Starter Kit is $115 in plastic bottles or $145 in glass, a $30 premium for skipping plastic packaging on the bottles themselves (Oct 2026). That upfront number is the real barrier, not the per-use cost, which is why this is a harder sell for someone testing one product than for someone ready to replace an entire cabinet at once. Amazon sells the Concentrate on its own as a Branch Basics Concentrate Refill 2-Pack: two 33.8 fl oz bottles, refill only, with the spray bottles sold separately (Oct 2026).
What not shipping water buys
A bottle of concentrate ships without the water that makes up most of a pre-mixed spray cleaner, which cuts weight and box volume directly. Branch Basics states on its own site that its refill model has prevented 14 million single-use plastic bottles from reaching landfills, and that not shipping water has prevented the release of more than 8 million pounds of CO2. Both are the company’s own reported figures rather than an independently audited count, and they describe the refill model in aggregate, not a guarantee about any individual order. The mechanism behind them, shipping concentrate instead of diluted liquid, is straightforward and verifiable even without the specific totals.
The same logic extends to Oxygen Boost, a two-ingredient laundry booster and stain remover sold as a powder rather than a liquid, which avoids shipping water twice over in a household that buys both products. It’s an add-on rather than a requirement, useful for stubborn stains and as a bleach alternative, but the core sustainability case rests on the Concentrate and its dilution ratios, not on how many companion products end up in the cart. The brand’s dishwasher tablets sit outside the Concentrate system too: they’re held together with a plant-based binder instead of a plastic film, and our non-toxic dishwasher detergent guide compares them with Blueland’s tablets and with film-wrapped pods.
For a plant-based option built specifically for stains rather than as an add-on, our plant-based stain remover guide compares dedicated pretreatment products.
The bottle material choice
The refillable spray bottles that hold the diluted cleaner are plastic by default; a glass version is available for $30 more on the Ultimate Starter Kit. Either bottle gets refilled from the same concentrate repeatedly rather than thrown out per use, so the plastic-vs-glass choice affects what one object is made of, not how often you’re buying new packaging. Anyone specifically avoiding plastic in the home should budget for the glass option; anyone optimizing for the lowest total packaging shouldn’t feel the plastic bottles undercut the concentrate model, since either way it’s the same bottle reused hundreds of times.
Ingredients and certifications
The Concentrate’s full ingredient list, per Branch Basics’ own product page: water, decyl glucoside, coco-glucoside, chamomile flower extract, sodium citrate, sodium bicarbonate, and sodium gluconate. Oxygen Boost is just sodium percarbonate and sodium bicarbonate. The formula is certified as a non-fragrance product, though the company’s own FAQ notes the concentrate still has a mild, soapy scent and some people detect a hint of chamomile, worth knowing if “completely scent-free” is a hard requirement rather than “no added fragrance.” Branch Basics lists its products as EWG Verified, MADE SAFE Certified, and Leaping Bunny certified, three separate third-party marks covering ingredient screening, safety standards, and animal-testing policy respectively.
Who it fits
Branch Basics makes the most sense for a household ready to replace most of its cleaning cabinet at once and willing to eat the upfront kit cost to unlock the cheap per-refill economics. It’s a worse fit for someone who wants to trial a single spray bottle before committing, since there’s no cheap single-bottle entry point, the smallest option is still a multi-bottle kit built around one concentrate. It’s also a worse fit for anyone who needs a registered disinfectant: the concentrate cleans but isn’t EPA-registered to disinfect, so sick-season cleaning still needs a second product on hand.
