What Is PureNase?

Using only pure, clean water and gentle pressure, the medical-grade PureNase device promises to help provide relief from sinus pain and congestion in minutes, which can last for days. How’s it work?

PureNase consists of two main parts: the tabletop unit, which creates steam and provides gentle pressure, and the attached hose, which delivers heat, steam, and pressure to all four of your paranasal sinuses. The process works over three steps:

  1. After filling the tank and turning the device on, PureNase heats the water to precisely 109.4°F, creating a therapeutic steam. Gentle pressure is also created.
  2. Next, you’ll hold the nozzle a comfortable distance from your nose and breathe normally for the next 20 minutes.
  3. PureNase can be used 2-3 times per week if you suffer from severe colds or allergies, with each treatment lasting up to several days.

Previously only available at doctors’ offices, PureNase claims to now provide congestion, pressure, and pain relief in the comfort of your own home.

And because it doesn’t use harsh chemicals, the company tells us PureNase is safe to use for even the youngest member of your family, with no side effects.

According to the CDC, nearly 30 million Americans suffer from chronic sinusitis (inflammation or swelling of sinus tissue) each year, while the AAFA reports that 50 million are affected by nasal allergies.

Whatever’s causing your sinus problems, though, can you expect meaningful relief from PureNase? Will it deliver a solid value? Here, we’ll help you find some answers to these important questions.

How Much Does PureNase Cost? When Will It Be Available?

As of writing, PureNase wasn’t scheduled for release until April 2017, and no prices were listed on the device’s website.

Upon release, we’re told that PureNase will come with a free adjustable nozzle and premium hose, along with a 60-day risk-free trial (return postage may be required) and a lifetime warranty against defects in materials or workmanship arising in connection with the normal and intended use.

PureNase’s customer support can be reached at 800-228-1306 or success@PureNase.com. We sent an email inquiring about expected price and will update this article as soon as a response is received.

First, What’s the Difference Between PureNase & RhinoTherm?

Before diving in, it’s important to note that, while the PureNase brand name was trademarked in April 2016, this basic technology has been around since the 1980s.

The first generation of this device was known as RhinoTherm. It was developed around the Weizmann Institute of Science’s hyperthermia technology, which has been clinically tested to address benign prostatic hyperplasia (BPH) and prostate cancer and retailed for about $1,000.

Using this same technology to treat nasal congestion, the company tells us that more than 25,000 RhinoTherm devices have been sold to clinics in the US and other locations to date.

Today, the RhinoTherm platform is owned by RhinoCare Ltd., who has updated and improved the original version of the product. RhinoCare Ltd. was founded by Dan Shaham, who has extensive experience as a commercial entrepreneur in the medical field.

Now, let’s get to the nitty-gritty!

The Big Question: Is PureNase’s Large Particle Vapor Treatment Clinically Effective for Clearing Sinuses?

On the PureNase website, the company lists five clinical studies to support their claims (all completed with the original RhinoTherm device):

  • A 1994 Wake Forest University study showing that three large particle vapor treatments per week reduced histamine concentrations for up to four hours, although not as well as nasal irrigation.
  • A 1985 study conducted in the Netherlands showing that PureNase reduced congestion, sneezing, cough, and itching. No third-party copies were available for review.
  • A 1980 study conducted at The Weizmann Institute of Science showing a 72% success rate for cold symptom elimination. Again, no third-party resources were available.
  • A 1994 Israeli study indicating that hot, humidified air did not impact viral shedding related to colds, although it did seem to improve symptoms like congestion.
  • Finally, a 1985 Italian study indicating that hyperthermia caused a “complete recovery” of 69% of participants suffering from rhinitis.

Pro tip: Although the PureNase website notes the device heats air to 109.4°F, we didn’t encounter anything clinically significant about this temperature during our research, as relates to congestion.

Taken together, it certainly seems like the hyperthermia (a fancy way of referencing elevated temperature) may help reduce congestion-related symptoms. However, it’s important to point out that a handful of studies does not make something “proven.”

In order to accomplish this, a device needs dozens (perhaps even hundreds) of double-blind, randomized studies that repeat these same findings.

What Causes Congestion? How Might PureNase’s Steam & Pressure Help?

The reality is that if you suffer from chronic congestion, it probably doesn’t come as any surprise that hot steam helps temporarily relieve symptoms. Why?

From a physical perspective, congestion is caused by inflamed blood vessels, which results in the tissue lining of your nose becoming swollen. As a result, this tissue may produce excess drainage, leading to a runny nose.

When you inhale steam, the hot air can help boost circulation, which then helps temporarily relieve the swelling and irritation and opens up your nasal passages. The water vapor can also help keep your nasal passages moist and reduce irritation.

However, this effect is short-lived, because steam doesn’t address the root causes of inflammation. A few examples include allergies, common cold, dry air, hormonal changes, drug and alcohol consumption, tobacco use, asthma, and even stress.

In other words, soon after inhaling steam, the underlying trigger causing your nasal inflammation will once again take hold, leading to continued congestion.

With PureNase’s added gentle pressure, it seems reasonable to believe that it might provide longer-term relief than a traditional steam treatment, like placing your head over a bowl of hot water. Note: We didn’t test the device firsthand to confirm this.

However, PureNase still won’t address the cause of your inflammation, so without making additional changes such as medication (specifically, decongestants or antihistamines), manually irrigating using a neti pot or devices like the Navage Nose Cleaner, or drinking lots of water, you can almost certainly expect your inflammation to return.

Remember, though: There are perhaps hundreds of causes of congestion, so be sure to speak with your doctor first. They can recommend options suited to your specific diagnosis.

Is PureNase a unique device, or is it swimming in competition?

Are There Other Devices Like PureNase?

While we didn’t find anything designed exactly like PureNase during our research, we found dozens of nasal steamers available online, some of which are available at national retailers for as little as $20.

While we don’t know PureNase’s price, we do know that most of these competing devices don’t provide gentle pressure, so we’ll just have to wait until its release to see how much this additional feature will cost customers—and whether it’ll deliver meaningfully more value and congestion relief.

Bottom Line: Can You Expect Relief From PureNase?

Millions of us suffer from chronic congestion each year, leading to missed work, reduced productivity, and spending less time with our friends and family. In fact, sinus infections are one of the top reasons doctors in the US prescribe antibiotics to patients.

If you’re sick (no pun intended) of taking medications and spending a fortune on doctor’s visits, should you think of PureNase as a viable option?

According to US News, the fact of the matter is that one treatment won’t address everyone’s needs—PureNase included.

Is it possible that the device’s combined steam and pressure will provide longer-lasting relief than traditional at-home methods? We don’t see why not.

But does this necessarily mean that PureNase will deliver a solid value for the money? There’s no way to know without giving it a try once it’s released in April. After all, the company seems to stand behind it with a 30-day refund policy, so you might not have more to lose than some money in return shipping charges.

But several important questions remain: Similar to some humidifiers, does PureNase use filters that require replacement? Are there any care concerns, such as the accumulation of mold? Can PureNase also be used to administer breathing medications, such as those for asthma?

In the meantime, what are your thoughts about PureNase? Did you ever use the previous RhinoTherm version in your doctor’s office? Whatever it is, be sure to tell us all about it in your review below!
