Important policies

Uninsured Services
OHIP pays for most medical services; however, some administrative services and medical procedures are not covered by OHIP. It is important to note that there will be a charge for these services. For a list of uninsured services please refer to the “Fees for Uninsured Services” available in our office.
Lab Results
You will receive a call to come in and discuss the results if the physician feels the need to discuss any aspect of your results. If a result comes back normal, you will not receive a call from the clinic. It is strict clinic policy that we do not provide results over the phone. Additionally, we will only provide lab results to patients. We will not provide patient results to anyone other than the patient. Please be aware that once the print out of the results leaves our clinic, we can no longer guarantee the confidentiality of the results, as it is now the patient’s responsibility.
Narcotics
It is clinic policy that we do not prescribe narcotics for walk in patients. For family patients, narcotics will only be prescribed on a short term basis and at the discretion of the physician.
Time
Routine appointments are approximately 10 minutes long. Please try to prioritize your problems and be as specific as possible as we are trying to manage our time appropriately.
Cancellation Policy
It is clinic policy that we require 24 hour notice to cancel an appointment. If a patient does not show up for an appointment or cancels in less than 24 hours the following procedure is followed: First missed appointment – a warning Every additional missed appointment – the patient will be required to pay a $50 charge

  • Incredible service and they have gone out of their way to make sure I have everything I need and continue to do so. Even when I moved to Vancouver Island, I still use PureFlow in Pickering and they send me all my supplies every 6 months, no questions asked. I would recommend them to anyone and everyone!

  • I've had dealings with about a dozen CPAP clinics over the years and this is by far the best one. The customer service is simply on another level. These guys truly take care of you. What I love the best about this place is that instead of pushing for you to buy the most expensive product, they suggest a product that's truly the best fit for your unique needs. They are not in the profit-maximizing business, they are there to help you and care for your needs.

  • Just perfect service! The clinic is very modern, it is very pleasant to be there. Plenty of free parking. The first visit lasted as much as an hour and a half. The technician was patiently selecting masks for me (not a simple task since they have a wide choice of excellent masks). He also explained in detail how to use the device. In the first days of my new life without drowsiness, the technician called me every morning and we discussed current affairs. If I had a problem or a question, I sent him an email and he always called back. In short, I highly recommend these guys!

  • My experience with PureFlow Clinic is a very positive one. It is in a very modern, clean environment. The staff is friendly and very professional. The owner Uri Kayumov is a very nice, knowledgeable person and you have a sense that although this is business, he genuinely cares for his clients.

  • Arnie is extremely helpful and knowledgeable . I have been going to PureFlow for over a year for my sleep apnea. I highly recommend this clinic.

  • I choose to go to PureFlow Healthcare just because of the positive reviews I have read here on Google vs the reviews of other CPAP clinics in the relative area. I have to say that I was not disappointed. It takes about 90 minutes to go over everything on the first time, so a Saturday time slot is great when the alternate is taking time off work. I met with Uri and he explained everything to me clearly. He knows his stuff -- as the owner should -- but he was more than just "selling" me on CPAP, he made sure things would be good for me to use and that I would be comfortable with things. After using the machine for a week, I had questions about the mask and called back. I made an appointment to go back in to see about another mask type and try that out so I can have the mask that would work the best for me. Overall, PureFlow really cares and they are not there to pressure you into a CPAP machine or this accessory over another. I am happy to have found this place.
