In my experience NovaFlow works better than over the counter sprays or allergy pills. I’ve been using it for 6 months 2x a day and have had very good results here in our high altitude dry climate. It’s easy to use and the charge lasts a long time. No more OTC pill drowsiness and dryness caused by pills and sprays. Novaflow is a better alternative and it’s backed by super customer service. Try it, I think you’ll like it.

I can't praise the NovaFlow and Cleriva enough!
Real person here and i cannot praise this little item enough!
For just short of 2 years I've been seeing an ENT Dr, about my sinuses and headaches, ive had cameras, drops (yes nasal drops) sprays, tablets the lot, and i seemed to get a little relief (around 20%) but then i came across an Advert for the Cleriva NovaFlow, i ummmed and ahhed for a bit, researched it, (even the cheaper versions) but i decided because my headaches were getting me down so much that i would plunge for the REAL thing, not cheap knock offs, and i am so glad i did! This brilliant device is keeping my sinuses clear and my headaches have gone! I am more than happy that i bought the real thing, i personally do not think that it is expensive for what it does!
My ENT prescriptions were £20 - £30 per visit, and now i have no more prescription bills as this NovaFlow device has sorted my problem! I am mire than happy to use this brilliant device twice a day for the rest of my life!
You HAVE to try it, be true to yourself and use it at least twice daily, (not just when you feel like it, something we are all guilty of) and hopefully like me, you will get the relief it is made for.
I did have a little problem with mine and i contacted Cleriva and they got back to me within the hour with a solution that i am more than happy with! They care! So this is a reputable company. Which are hard to find these days, real people at the other end of the email, no automated response, just 100% help. Honestly i cannot recommend this device and company enough.

Don't waste your money
I can't say this product doesn't work at all because you can't do a controlled study on yourself. And of course there's always the placebo effect. Certainly it is not the panacea it's advertised to be. I still need to use most of my other meds. As for the device itself, it's clear that this is a rebranded piece of Chinese junk. The product is shipped directly from China with no usage instructions whatsoever for anything included in the box other than meaningless statements converted from Chinese to English. It comes with a bunch of pieces that you'll simply have to figure out yourself what to do with. No American manufacturer gave any thought to how this was packaged or how you might even think to use all the parts. The power plug is an ancient USB-B which does nothing to reduce weight or power requirements compared to USB-C, it's just an old interface. It's indicative of the Chinese manufacturing era it comes from, and the fact that this device is simply rebranded. If you want to try red light therapy you can buy an identical device (without the branding) on Amazon for $15 instead of paying $50. And if you test the light frequency with a simply meter you'll find that they are all tuned to the "special" red 660nm frequency. You may or may not experience any small benefit, but don't waste your money on something with special branding that advertises all over social media.
Response from ClerivaMay 12, 2026
Hi Jay, thanks for your honest review and we’re sorry the product didn’t work for you. Red light therapy isn’t a guaranteed solution for everyone, and we try to be transparent about that. NovaFlow is a wellness device, not a medical device or cure, which is why we don’t provide clinical instructions beyond standard usage guidance.
We also want to clarify a few points about the product itself. While there are many similar-looking red light devices online, they are not the same NovaFlow devices. We have our own manufacturing team that quality inspects each batch before fulfillment. With lower-cost alternatives, wavelength consistency and build quality can vary significantly from unit to unit.
And unlike the cheaper alternatives, we stand behind our products with a 120-day return policy because we understand it may not be the right fit for everyone.
As for the USB connection, we chose that design intentionally to keep the device lightweight, comfortable, and easy to wear during sessions. Moving to USB-C would have required a larger internal battery and heavier hardware, which would make it a lot more uncomfortable.
We genuinely appreciate the feedback and are always working to improve both the product and the customer experience. If you haven't already, reach out to our support team at [email protected] and we'll set you up with your free refund!
