I had some questions about usage for the product, and the customer service rep, "Coney", was outstanding in walking me through the process. He was prompt in replying, professional, warm and friendly, knew his stuff, and was able to quickly address my questions and wisely direct me, fully taking care of my problem. I am very impressed with the Cleriva customer service - I was treated kindly and with respect. I will continue to use Cleriva products!

Don't even bother
Ordered 14th Jan, waited 6 days for a tracking number (20th Jan) 30th Jan, no movement whatsoever on the tracking, basically a "label created" situation. contacted customer services, got a copy and paste reply telling me how to track. the parcel was lost, i knew it was lost but they weren't willing to help. had to report to my bank to get the refund sorted. foreign set up, could tell customer service replies were AI or non english speaking.

Hi John,
I’m truly sorry for the experience you’ve had. I completely understand how frustrating and disappointing it is to wait so long with little to no tracking movement, especially after reaching out for help. Upon checking, your parcel did experience delays in transit due to high shipment volumes, but I can confirm the latest update shows: 2026-01-30 07:54:00 - ARRIVED AT DESTINATION AIRPORT. This means your package has now reached the destination country and is moving into the final delivery stage. Once Royal Mail scans it into their system, you’ll begin receiving regular tracking updates along with an estimated delivery date.
That said, since you requested a full refund, I want to confirm that we have successfully processed your full refund. Depending on your bank, the amount should reflect back to your account within 3–5 business days. If the package still arrives, please feel free to keep and use it or discard it, as we do not accept returns for used or unused devices for hygiene reasons.
Lastly, I just want to reassure you that you are speaking with a real person. I’m truly sorry again for this inconvenience. If you have any questions at all, you can always reach me directly at [email protected], and I’ll gladly assist you right away.

Effective but incomplete
I ordered this 11/01, and received it on 24/01, so a bit of a wait but not too bad. It would be helpful to see the estimated shipping times on the order, as is usually the case.
I didn't have big sinus or breathing issues, but just chronic PND. I've been using it for about 5 days, and it is definitely helping. My nose is clearer, and there is less mucus in my throat. It's easy to use, not unpleasant at all, and I am delighted to carry on doing so.
My one concern is that it does not come with any container or cleaning methods - these have to be purchased separately. The instructions otherwise - 'clean with a damp cloth' - are quite inadequate, in my opinion. The website advises against any other method of cleaning, but doesn't say how this alone could possibly be effective.
I have ordered the sterilising case, but will now have to wait another 2 weeks for that, plus paying extra shipping costs. I think it should be made clear that this is necessary, and therefore it should be included with the device as a package, even although this would cost more. It seems disingenuous to pretend it is not needed.

Incredible service – Cleriva replaced a competitor's faulty product!
I had a frustrating experience buying a rhinitis device from a Facebook/Shopify ad (not realizing it wasn't a genuine NovaFlow). I ended up with a cheap, unbranded device that felt unsafe.
I reached out to Cleriva for advice, and their support team was amazing. They explained the safety risks of using unverified devices and, to my surprise, offered to send me a genuine NovaFlow device to ensure I had a safe and effective experience. It’s rare to find a company that cares this much about consumer safety and brand reputation. I’m now a loyal customer!

Novaflow has been a life changer
I've been using the novaflow for less than a month and the constant dry nose accompanied by bleeding has completely resolved. I can breathe easy, don't sneeze constantly and my nightime snoring has hugely reduced. No longer any need to use prescribed steroid nasal spray. I contacted the company to check if it's safe to use the device without the protective sleeves (as I gave very small nostrils) and got a speedy response.

Glad i took a chance on this
I’ve been using NovaFlow for over 2 weeks now and so far have been really impressed with the results. After using it on day 1 i could noticeably breathe more easily, but still felt the congestion pressure. But after a couple of days that congestion feeling went. The biggest differences i can notice are being able to breathe through both nostrils, at the same time! It’s quite a novelty, i’ve only ever been able to do that with nasal sprays previously. Also just breathing normally there doesn’t feel like any obstructions where previously i always felt like i wasn’t getting enough air in.
I haven’t been waking up with a horribly dry mouth in the night either from mouth breathing.
I would absolutely recommend this to anyone who struggles with sinus problems. I’ll take a glowing red face a few times a day for these results!

Good buy; great customer service!
I purchased the NovaFlow in late December after years of sinus issues, rinsing every day, and taking allergy medications. I did notice the first time I used it my nose felt less full and clogged. I’ve been using it once a day and have noticed my nose being less stuffy. I am also a cpap user who couldn’t sleep on my side due to my nose being continually clogged on one side. I can now sleep on my side again.
I do want to note that the customer service was quick and responsive; my pup decided it looked like a chew toy. I contacted the rep and they immediately worked with me to help me out. Thank you!

I've been using my new NovaFlow, & I think I've FINALLY found something to work for my NON-allergic rhinitis!
I've been using my new NovaFlow red laser nasal therapy for just over a week for my non-allergic rhinitis, post-nasal drip, and sinus pressure in all my sinuses. I also have a perforated septum, so my sinus irrigation just flows straight through the hole & not into my sinuses. I'm starting to be able to tell a real difference. It's the dead cold of winter, but my nose isn't runny & having to blow my nose every 30 minutes as usual. No, just a few times a day really. It isn't uncomfortable to use, & each session (I'm using it twice a day) is about 10 minutes long. I got the kit with the UV sterilizer, extra nasal tips, & carrying case. The carrying case is way too large for my liking. The UV sterilizer does a good job I assume, as it has 2 UV LEDs & a viewing window. It's rather strange that the device charges with an ancient micro-USB charger, but the UV sterilizer uses USB-C. C'mon, get with the times! This is 2026! micro-USB is a thing of the past! That's really the only complaint that I have about the device & kit so far. Time will tell if I'm able to get off the 2 antihistamines & the Flonase I use twice a day, every day. Thanks for showing me something in a Facebook ad that I didn't know that I needed! I scrolled right past the ad several times, but I'm glad that you were persistent. I really think this is going to work after DECADES of doing the same old crap with antihistamines and steroids, KNOWING that they don't work with NON-allergic rhinitis, which is the diagnosis I received after 2 rounds of allergy testing about 6 years ago! I spent over 30 years taking meds that COULDN'T help!
