The first of its kind
The only nasal irrigator with two synchronised pumps for true rinse-and-suction action.
Why saline works
Saline physically removes mucus, allergens, and viral particles from your nasal passages.
Real results
Most customers report meaningful relief in their first session, with full effects in 1–2 weeks.
Rinse your way
With two pressure levels and any saline you choose, your routine fits your face.
+Based on customer surveys.
Studied for 50 years.
Daily nasal rinses are backed by decades of peer-reviewed research from major medical institutions. We didn’t invent the practice. We just made it doable.
Study i.
“Nasal rinses can reduce both symptom severity and the duration of a cold.”
Study ii.
“91% of physicians recommend nasal irrigation for chronic rhinosinusitis. 77% recommend it before antibiotics.”
Study iii.
“In an 871-patient trial, daily nasal irrigation was more effective than steam over six months.”
How it works?
Order your kit
Pick The Kit or The Essential. Free worldwide shipping.
Set up in two minutes
Charge over USB-C, fill with saline, and you’re ready. Illustrated guide included.
Rinse for thirty seconds
Press the button, switch nostrils after fifteen seconds. Done before you’ve thought about it.
Make it daily
The clinical evidence is built around consistent daily use. Chronic conditions shift in 1–2 weeks.
The hidden cost of “the other one.”
Most competitors use proprietary refills. The device is the small purchase. Here’s what five years actually looks like.

Endday · The Kit
$849
over five years
Kit + saline subscription at $10/month. Or use any saline you want.
That’s over $1,200 in your pocket over five years — roughly the cost of a long weekend away or 130 flat whites.
Built like a medical device.
Used like a daily one.
For the engineers and the curious. Here’s what’s under the hood.
Dual-pump rinse and suction
Squeeze bottles use one. Ours uses both at once.
Faster than your morning coffee
Fifteen seconds per nostril. Done before you’ve thought about it.
Plug it in once a month
USB-C charging from any phone cable. Travel-friendly.
Soft & Clean
Start soft if you’re new. Work up as tolerance builds.

Built for people who recognise themselves.
This product isn’t for everyone. But if any of these describe you, it was made with you in mind.
Wake up congested
Daily morning blockage that takes thirty minutes to shift before you can think clearly.
Live with seasonal allergies
Spring or autumn pollen takes you out for weeks. You’re tired of being on antihistamines.
Get recurring infections
Antibiotics for sinus issues more than once. Your ENT keeps recommending rinses.
Travel often
Flights and dry hotel air leave you a wreck. Your sinuses pay the price.

A note from our founder
I built Clearflow because I was tired of squeeze bottles, tired of antihistamines, tired of products that treat the symptom and not the routine.
Founder, Endday
Get complete support.
Your purchase comes with everything you need to make daily rinsing actually stick.
Where this isn’t right for you.
If you have an active sinus infection, see your GP first. This supports recovery, not acute treatment.
If you have a perforated eardrum or recent ear surgery, talk to your ENT before using any nasal irrigation device.
If you’re under 12, this isn’t designed for you.
If you’ve never had a single congested day, you don’t need this.
If you’re expecting a miracle in five minutes, manage expectations. Chronic conditions take weeks.
We’d rather lose a sale than have a customer who shouldn’t be using the product. That’s why the 30-day Returns Pact exists.
The questions most people ask.
If yours isn’t here, our customer service team is available during business hours.
Is this safe to use every day? ⌄
Yes. Daily nasal irrigation is recommended by international ENT guidelines for chronic sinus and allergy sufferers.
Consult a doctor first only if you have active sinus infections, perforated eardrums, or recent ear or sinus surgery.
What kind of saline can I use? ⌄
Anything. We make Clearflow saline packets because they’re convenient and pre-portioned, but the device works with NeilMed sachets, Flo Saline, generic pharmacy saline, or homemade isotonic solution. You’re never locked in.
How long until I notice a difference? ⌄
Most customers report relief in their first session. Chronic conditions shift over 1–2 weeks of daily use.
How is this different from a squeeze bottle? ⌄
Squeeze bottles use one-directional pressure. Ours uses two synchronised pumps — rinsing and suctioning simultaneously — in half the time.
What if it stops working? ⌄
Two-year warranty, no asterisks. Email support@endday.co and we’ll handle it within 24 hours.
A little innovation.
The same intervention your ENT recommends — shrunk into thirty seconds and built for your bathroom shelf.
