Unfortunately, the Novaflow product did not work for me due to some previous surgeries and procedures that I've had years ago. (Turbinectomy/Polyp removal/etc). However, I really did want to try the product in the hopes that it might get me some congestion relief. After trying it for a few months without positive results, I reached out to the company to request the 120 day money back guarantee. I worked with Coney, who was very understanding with the conversation and had no issue at all honouring the refund. I received it within a couple of business days...fully repaid to my CC. I really wish that the product could have worked for me, but the next best thing is to have the business stand behind their product and refund the amount as promised. Well done! If you're considering it...I would suggest you give it a go...as you have nothing to lose! Thanks again, Coney!

Excellent device and support.
I was initially quite skeptical, but was willing to give it a try. I was delighted to find improvement in my symptoms in a couple of days and it's been a huge help with my sleep especially in the months since then. When my battery capacity seemed to be declining faster than expected, I got quick and very helpful response from Coney in the support team. Thank you!

A Breath of Fresh Air in every sense.
I’ve been using the Cleriva NovaFlow red light device for the past 10 days, and I’m genuinely impressed with the results so far.
I’ve suffered from rhinitis for as long as I can remember, along with persistent hayfever that typically lasts from March through to late October. Nasal congestion has always been a daily struggle for me. However, since using the NovaFlow, I’ve noticed a significant improvement—my nasal passages feel clear, and I can breathe freely through my nose, which is something I haven’t experienced in years.
In addition to the product itself, I’ve also been very pleased with the customer support. I contacted Cleriva regarding the Ultraviolet Sanitizer unit I purchased alongside the NovaFlow, and both Maddy and Coney responded quickly. They were friendly, helpful, and thorough in answering my questions—truly a breath of fresh air.
So far, I’m extremely happy with both the product and the service.

I was sceptical…
I was sceptical that this would work for long term sinus issues including a post nasal drip but this has helped me tremendously. I use it every day, up to 3 times if feel slightly blocked up and have not been having the same sinus headaches or nasal congestion or discharge as before starting to use it a couple of months ago.
It did take a couple weeks to be delivered but it was worth the wait.
