Frequently Asked Questions

Question:  Does the silver ion coating clean your hands?

No it does not clean your hands. Instead it kills the germs deposited onto the coated surface that would otherwise contaminate your hands when you open the door. This allows you to open the door without worrying about picking up lots of nasty germs from the door handle or push plate. 

Question:  If it doesn’t clean hands, what’s the point?                        
It’s true that the product doesn’t actually clean hands. Someone with dirty hands will still walk around your site and contaminate lots of objects. However, it’s much better than every user picking up germs from the door handle or push plate and spreading them around the building, especially when common Microbes found on door furniture include E-Coli, Salmonella, Campylobacter and Staph Aureus. 1 in 100 people with dirty hands is much better than 100 out of 100 people all spreading germs and making everyone ill. 


Question:  What if the person before me hasn’t washed their hands – will I pick up their germs?
It’s inevitable that some users will not wash their hands. Fortunately the silver ions work immediately to break down the germs and protect the next user. Independent field trials undertaken in an office of 85 people have proven that the Purehold coated surfaces are 96.4% cleaner than standard door handles and push plates, giving users complete peace of mind.


Question:  What if I have damp hands and use it?
Damp hands are ok because Purehold coated surfaces contains very few germs so you are very unlikely to contaminate your hands. However, if you use a normal door handle or push plate with wet hands you are extremely likely to pick up thousands of bacteria from the surface, including E-Coli, Salmonella, Campylobacter and Staph Aureus. Statistically, damp hands are 1,000 times more likely to spread bacteria than dry hands so letting users touch dirty door handles and push plates with wet hands is a sure way to spread germs throughout a building.


Question:  I don’t believe it works!
It’s certainly hard to believe when the technology is invisible. However, the antibacterial properties of silver ions are extremely well known in the industry. To prove it, we have undertaken extensive Independent tests and field trials. The antibacterial coating has been independently tested in the lab to the most recognised industry standard (ISO 22196:2011 - Measurement of antibacterial activity on plastics and other non-porous surfaces). We have also undertaken independent field trials in an office of 85 people and 3 very high use doors. Results showed that the Purehold coated surfaced were 96.4% cleaner than standard door handles and push plates. If you still don’t believe us, we are happy to share the 80 page Technical Report which outlines all of the independent testing undertaken. This contains full details of the test procedures, results and which laboratories were involved.


Question:  How do I know when it needs changing?
This is very straight forward - each product has an indicator will gradually turn from white to red over time. As soon as you start seeing red appear it’s time to start thinking about ordering replacements.


Question:  Will the Purehold PUSH plate fit on any door?
The Purehold PUSH plates will fit on almost any door - just remove the original push plate and replace it with the Purehold PUSH. CLICK HERE to watch the Purehold PUSH installaion video


Question:  What door handles does the PULL handle fit?
It will fit the 3 most common cylindrical pull door handle (often called “D” Handles) in the UK with a diameter of 19mm, 20mm or 22mm. If you are unsure please ask and we can send you a plastic gauge to measure. A measuring gauge is provided in the box with every pull handle as standard so you can check when it arrives. CLICK HERE to watch the Purehold PULL installaion video


Question:  Most of our doors have “Lever style” (i.e. push downwards) door handle – will the Purehold PULL fit these?
Unfortunately not. The product only works with standard pull handles (i.e. “D” handles). However, we are developing a new lever handle version which will be available in 2018.


Question:  Our pull door handles are the wrong size and shape – what can we do?
There are a couple of options. We can either supply you with new D shaped pull door handles for you to fit yourself  or we can arrange for our engineer to come to site and fit standard D shaped pull door handles for you. There would be a small charge but given the benefits of reducing staff sickness, it’s well worth it.


Question:  How often should the PULL handles and PUSH plates it be cleaned?
We would recommend you clean them in line with your normal routine for door cleaning and that you use a soapy water to wipe them down. Unlike other products, the PUSH and PULL work continually to kill germs using the silver ions to kill germs so they do not require any disinfectant chemicals to clean them.


Question:  How cost effective are they?
Very. If they can prevent one member of staff from going sick they more than pay for themselves for the entire year. Not only that, they also improve the aesthetic look of the doors and give staff, customers and visitors confidence that they are touching a clean surface.


Question:  How easy are they to fit?
Both the PUSH and PULL are very easy to install can be fitted in under 60 seconds and require no tools. Click below to watch watch our simple installation videos :


Question:  How strong/robust are they?
All products are are very robust .

  • The PULL & LEVER handles will easily last 6 months on a high traffic doors, and testing has shown the coating is effective for approximately 6 months and is based on usage of between 50,000 and 100,000 pulls. 

  • The PUSH plates will easily last 12 months on a high traffic doors, and testing has shown the coating is effective for approximately 12 months.
