Epurair Deluxe HRV 95: Overview
Purahome’s TOP Choice as Best Compact Heat Recovery Ventilator (HRV) – Epurair HRV95
Purahome is very pleased with (now a 3rd Generation Model, we have installed the previous generations and they were all good) the newly redesigned Epurair HRV 95. A tour of the Epurair manufacturing facility revealed hi-tech laser equipment for precision metal-cutting, very different than many manufacturers who rely on fold and rivet construction. The new design incorporates much thought that has helped eliminate many of the shortcomings of competitive HRVs.
After many diverse installations, our testing revealed:
• Electronic balancing of fan speeds (fresh air in and stale air out) results in quieter, smooth ventilation
• every single installation to date has significantly improved our customers’ air quality
• customers were getting exciting results in real-time, real-world testing situations at work and home
Because of a large focus on energy conservation in the early 1980’s, new building codes were implemented in order to reduce energy consumption, The new codes called for higher insulated values. As a result, new homes, buildings, additions and even remodeling projects are being built far more airtight than they used to be.
People started complaining of headaches, nausea, fatigue and dizziness in the workplace. By the 1990’s people were experiencing similar symptoms in their own newly built homes. This is when the term “Sick Building Syndrome (SBS)” was developed. 
Improved design that includes better insulation has significantly reduced drafts and energy consumption for heating resulted in building a “tight” home to today's standards with reduced overall heat loss by 25 to 50%. This is great for saving money and energy but downright dangerous for our health! This is why every November is Purahome’s busiest month of the year – an air tight home becomes very apparent when a furnace starts to run. One of the most critical and underestimated aspects of newer buildings and homes is ventilation control.

The ventilation rate of a traditionally older drafty home is determined by a few things. For example, the colder and windier it gets, the better ventilated your home is. In drafty old homes, this process occurs naturally, as untreated air is drawn in. If your home, however, is airtight because it was built within the last 15 years or so, (read this section twice as it is scary), it can take as long as 10 hours for one air exchange! Compare this to a recommended ventilation of one air exchange every three hours or so to alleviate “Sick Building Syndrome”. Oxygen consumed is not being replaced and VOC gases accumulate in your indoor space.
For people who want the cleanest air as free from gases, odours and humidity (in the winter) as possible especially where tight quarts are present for installation, we highly recommend the Epurair HRV 95 Heat Recovery Ventilator. Individuals sensitized to airborne gases such as formaldehyde, benzene and other VOCs that off-gas will drastically reduce indoor exposure to these gases by using an Epurair HRV.
NOTE – In this job for Dan Grabowski Denture Clinic, we created a negative pressure in tha back of the clinic where the chemicals are mixed and dentures grinded. We also created a positive pressure in the front area waiting room with fresh air from the Epurair HRV 95 to help prevent any odours infiltrating to the front. We also installed an Abatement CAP 600 HEPA to lower the particulate in the entire space.
“We are very happy with the air! We find it so much easier to breathe now in our work environment. In running my denture clinic, I developed a lingering dry cough. Whenever my wife would push gently on my chest, it forced me to cough. Ever since the install of our HRV and HEPA in our Denture Clinic, my dry cough has disappeared! I feel better.
Odours and chemical vapours from the lab and also the eating area would permeate into the front customer waiting room. This problem no longer exists because of the air exchange and air distribution designed by Purahome for inside our clinic. customer installs + testimonials> done-denture clinic
I also noticed another benefit. By the end of the working day, I used to have to wipe my eyes to remove the particle buildup from my tear-drop glands. Now, at the end of the working day, I no longer have this issue! We are very happy!” Dan Grabowski
Did You Know?
According to the CMHC in Canada, approximately 90% of installed HRVs are not balanced and not maintained! Purahome has to agree with this finding. We have been into many homes with an existing HRV to provide healthier air and when we quiz the homeowner about it, they do not typically know how it works and what to do for maintenance. Purahome customers are educated on their HRVs, know what information to provide us if they wish to slightly adjust any user settings and are called annually for their replacement filter kits that include our GREEN Microgerme Sanitizing Cleaner.
Epurair Deluxe HRV 95: Features and Applications
What Makes the Epurair HRV 95 a Purahome First Choice Winner?
The Epurair HRV 95 advanced performance and features make it a Purahome First Choice for individuals looking for ventilation with heat recovery and total user control. These features include:
1. Low Speed Electronic Balancing – Purahome’s Favourite Feature!
This process is very unique indeed and only Greentek HRVs have a similar technology. Every HRV installation requires balancing the system meaning air flow coming into your home and air being exhausted from your home are within 10% of one another. You’re your Epurair HRV 95, air flow gets balanced by simply adjusting the fan/motor speed for intake and exhaust up to plus/minus 10%. In many cases, this prevents the use of additional mechanical dampers. This makes every Epruair HRV installation more silent and economical. By reducing motor speed to balance the unit you are reducing the noise that would be produced by balancing dampers. In addition, with this GREEN technology the Epurair HRV will consume less energy than comparable sized HRVs.
2. Compact Size With 5” Top Ports – Installable Almost Anywhere!
The Epurair Compact Design has saved us (and our customers) time and time again as we were successfully able to install the Epurair HRV 95 in homes where no other HRV would work for the installation.
3. Low Maintenance & “No Tools” Filter Changes– This is Easy!
Your Epurair HRV will need your attention only twice a year! It is maintenance-free for up to six months at which time (NO TOOLS REQUIRED) you clean the heat recovery core by simply pulling it out and rinsing it in the laundry tub. Only Purahome offers annual filter kits for Epurair HRVs that include our Microgerme Sanitizing GREEN cleaner to help sanitize your core. The GREEN Carbon filter pads get changed twice a year.
4. German-Engineered Motors – Maintenance Free and Better Performance
Your Epurair HRV 95 is designed with high performance and reliable German-Engineered fan/motors. Factory sealed and dynamically balanced, these motors are maintenance free for many years. The backward inclined motor blades offer a high air flow efficiency. The fan/motors are also permanently lubricated and have a very low energy consumption – 65 Watts Maximum (like a light bulb). Purahome really likes how Epurair has used voltage variation for the speed control of both fan motors in order to help balance the HRV system.
5. Intelligent Design – Easy Access, Easy To Clean, Easy to Operate!
Your Epurair HRV 95 is the result of Engineering design based on knowing the shortcomings of all other HRVs and their installations. The HRV Door opens sideways for much easier access to the inside. There is no obstruction with the core removed for much easier cleaning. The Electronic Controls are simple for easy operation whenever an adjustment (that is, an increase or decrease in ventilation) needs to be made.
Applications – How Can It Help Me?
Molecular control
• Volatile Organic Compound (VOC) control
• Molecular (gaseous chemical) control
Odour control
• Pet odours
• Musty odours
• Cooking odours
• Paint odours
Why the Epurair HRV 95 excites us:
• Balancing is much more installer–friendly versus competitive HRVs.
• Customer Satisfaction is virtually assured.
• Service Calls are far and few between (only 2 to date in 6 years!).
• Advanced performance because of advanced features, that is, healthier air for our customers and peace of mind.
• Filters are easily changed without any tools and are available in a convenient annual filter kit whereas other HRVS have hard-to-find replacement filters.
• As is the case with any whole home air equipment installation, best results are achieved with the furnace fan running especially when a family member has a greater need for improved air quality. It is the customer’s choice whether to run the furnace fan 100% of the time or not, hydro costs will go up but air quality will be better (there are no free meals out there).
What we are not excited about:
• A thorough Installation Manual would make this more Installer–friendly although a Purahome Expert will guide any installation if needed.
• Only 1 Dehumidistat Control is available so no options here. We would like to see a little more attractively designed dehumidistat in case it is installed in an upper area of a home.
• For customers that wish to qualify for the EnerGuide rebate, the Epurair HRV would not qualify as it is not HVI certified (NOTE – this certification does not imply anything about performance)
Warranty: 5 years on the fan motors, Lifetime on the HRV Core, 2 Years on the electronic control board, 1 Year on all other components.
CONCLUSION *****/5
Purahome appreciates everything that has gone in to making your Epurair HRV an excellent system from Electronic Balancing to an Ideal Compact Design and Shape for almost anywhere-installation. They work great because they have been engineered properly! Purahome is convinced any Epurair HRV customer will live longer and healthier!
