This is the page where the product comes off best, and the reason is one division sum the brand never does for you.
Written by the Breathizen editorial team·Last updated October 11, 2026·How this page was checked
All three Breathizen prices were published in the pack supplied to this desk: $89 for one bottle, $177 for three at $59 each, and $294 for six at $49 each, against struck-through figures of $179, $537 and $1,074. The move that matters is the bottle life. A bottle is 2 oz / 60 mL and the serving is 0.60 mL, so a bottle is 100 days, not the thirty most buyers in this category assume. That makes the three packs $0.89, $0.59 and $0.49 a day, and $0.49 is the lowest per-day figure this desk has published for anything. Then the arithmetic turns. Six bottles is 600 days of product, about twenty months, bought against a 60-day refund window. The struck figures are simply $179 multiplied by one, three and six, with no date given on which anything sold at $179. Shipping cost is not published for any pack, and neither is delivery speed. No two-bottle pack is sold, although one of the ten supplied reviews reports buying two.
Three bottle counts, three published prices. The per-day figures are ours, and they depend entirely on a bottle being a hundred days rather than a month.
A hundred days, which already outruns the refund window by forty.

Three hundred days, about ten months, and the pack most of the ten supplied reviews bought.

Six hundred days — roughly twenty months — bought under a window that closes after sixty.

The struck-through figures are $179, $537 and $1,074 — which is $179 multiplied by one, three and six. A crossed-out price is a claim about what something used to sell for, and no date is given on which this product sold at $179 a bottle. We print the struck figures because they are on the offer, and we print this note beside them because a reader deserves to know they are arithmetic rather than history. · The money-back window runs from purchase, not from delivery · What that actually means
On most of the products this desk reads, this page is an exercise in writing down what nobody would say: a pack arrives with artwork, seals, a guarantee and no figure anywhere.
Not here. The pack supplied carries the complete price list, and it is worth printing in one place: $89 for one bottle; $177 for three, broken out as $59 a bottle; $294 for six, broken out as $49 a bottle. Beside each sits a struck figure: $179, $537, $1,074.
We score price transparency 4.0 out of 5 here, the second-highest row on our card, next to two rows scored zero. That is not a contradiction: a company can be entirely open about what it will charge and entirely closed about what you are buying.
Three packs, and only three. There is no two-bottle pack in anything supplied to this desk — no price, no render, no mention. We note it because one of the ten supplied reviews reports buying two bottles. We are not calling that review false; the buyer may have ordered twice. We are telling you the pack list we were given does not contain what one of its own reviewers says she bought.
And one money figure is missing. Shipping cost is not published for any of the three packs, and neither is delivery speed or international availability. So nothing here is a delivered price.
It can price the product to the cent, because the brand published the figures. It cannot price the order, because no shipping cost was published for any pack. Read the total on the payment screen before you pay.
If you take one thing from this site, take this. Two numbers, both printed on the product, and almost nobody does the sum.
The bottle is 2 oz / 60 mL and the serving is 0.60 mL, once a day, stated in the directions as four pumps. 60 mL ÷ 0.60 mL = 100 days. Not thirty. A bottle is more than three months of product.
That changes the whole price. The convention on this shelf is a thirty-day bottle, and at a glance $89 for a month reads as expensive. Run against the real supply, the packs are $0.89, $0.59 and $0.49 a day. Forty-nine cents is the lowest per-day figure this desk has published for anything, and we score cost per day 4.5 out of 5 because of it.
A reader who misses this sum misprices the product by more than three times. The brand does not do the division anywhere in the pack supplied to us, which is a strange thing to leave out.
Now the struck figures, which are arithmetic rather than history. $179, $537 and $1,074 are $179 multiplied by one, three and six. A crossed-out price is a claim about what something used to sell for, and no date is given on which this product sold at $179 a bottle. We print them because they are on the offer, and we print this sentence beside them for the same reason.
One more division worth doing. The comparable unit between products is the day, not the bottle: pack price, plus the shipping the checkout shows you, divided by 100, 300 or 600.
A hundred-day bottle at 49 cents a day is the best thing about this product by a distance, and it appears nowhere in the marketing supplied to us.

Everything above is the case for this product. Here is the same arithmetic run the other way, because a hundred-day bottle cuts both ways.
Six bottles is 600 days. The refund window is 60. Ten times the window in product, bought in one transaction. Even one bottle outlasts the window by forty days, so you cannot finish a single bottle inside the period in which you are allowed to change your mind.
And the brand's own timing eats most of what is left. The sales side asks for at least 30 days of use before a claim, and the review summary says most people wait three to six weeks. At six weeks you are 42 days in with 18 days left. So the cheapest pack is the one you must commit to longest while having the least time to judge it.
Three things about the guarantee are not stated anywhere. Whether an opened bottle qualifies. Whether a multi-pack can be partly returned. Whether a restocking fee applies. On a six-bottle box at $294 with buyer-paid return shipping, all three decide whether the window is worth anything. Ask on the phone before you buy six.
Then four things on the checkout screen, before the card details. The delivered total, including shipping, for the pack you are buying. The refund window, which should say 60 days from purchase; whichever length the checkout states is the one that binds, so screenshot it. Whether there is a subscription, since nothing supplied to us mentions autoship either way. And who you are paying, because no manufacturer or distributor is named anywhere on this product.
One disclosure to finish. This site is a Breathizen authorized U.S. retailer and we earn a commission on orders placed through it — which is why the paragraph about 600 days against a 60-day window sits on the page that sells the six-bottle pack.
One bottle, at $89. A hundred days, $0.89 a day, and the only tier that does not ask you to commit years of a product whose amounts nobody has published.
Almost every pricing page in this category has to hedge, because the label will not say how long a bottle lasts. This one does not have to.
The two numbers the sum needs are both published. The bottle is 2 oz / 60 mL on the front, and the directions name a serving of 0.60 mL once a day. 60 ÷ 0.60 is 100 days, so a bottle is a hundred days of product rather than the thirty this shelf assumes. That is not an estimate and it is not our inference; it is division on two printed figures.
So the cost per day finishes itself: divide by a hundred for one bottle, by three hundred for three, by six hundred for six. $0.89, $0.59 and $0.49. Write the number down before you decide, because a per-day figure is the only form in which two supplements can honestly be compared.
What the label cannot give you is the delivered total. No shipping cost was published for any of the three packs, and neither was delivery speed, so the figures above are pack prices rather than what will leave your account. That is the checkout's to tell you.
$89 for one bottle, $177 for three ($59 each) and $294 for six ($49 each), with struck-through figures of $179, $537 and $1,074. All of those were published in the pack supplied to this desk. Confirm at the live checkout.
$0.89, $0.59 and $0.49 for the one-, three- and six-bottle packs. Those figures depend entirely on getting the bottle life right: 60 mL at 0.60 mL a day is 100 days, not 30. Priced against an assumed monthly bottle you would be out by a factor of more than three.
They are $179, $537 and $1,074 — which is $179 multiplied by one, three and six. No date is given on which this product sold at $179 a bottle. We print them because they are on the offer, and we print this note because a crossed-out number is a claim about the past that almost nobody can check.
100 days. The bottle is 2 oz / 60 mL and the daily serving is 0.60 mL, so 60 ÷ 0.6 = 100. This is the one calculation the label lets you run, and most pages in this category assume a 30-day bottle.
We will not tell you which to buy, but the arithmetic is worth having. One bottle is $89 for 100 days and the only option that does not commit you to a year or more. Six bottles is the cheapest per day at $0.49 — and it is 600 days of a product with no published amounts, bought against a 60-day refund window. The window does not stretch to cover the supply.
Not published for any of the three packs in anything supplied to this desk, and neither is delivery speed or whether it ships outside the United States. It ships from the US unless the sales page says otherwise, and tracking arrives in the order email. Check the total at the checkout before you pay.
One bottle is 100 days against a 60-day window, so no pack can be finished inside it. The smallest is still the smallest bet: $89, $0.89 a day, and the only one that does not commit you to years of a product whose amounts are not published.
The struck-through figures are $179, $537 and $1,074 — which is $179 multiplied by one, three and six. A crossed-out price is a claim about what something used to sell for, and no date is given on which this product sold at $179 a bottle. We print the struck figures because they are on the offer, and we print this note beside them because a reader deserves to know they are arithmetic rather than history. · window runs from purchase · no subscription · not for under 18, pregnancy or nursingWritten and fact-checked by The Breathizenres Editorial Desk, last updated October 11, 2026.
