OCEAN REEF

Certified adaptations of full face masks to address COVID-19 CRISIS

Please note this webpage has been setup to answer common questions and address multiple matters as they arise to relieve our personnel of the many enquires. It will be updated frequently and information might change. We thank you for your patience and understanding.

OCEAN REEF to fight COVID19 

In the beginning of March, we deposited an international Patent through our Italian company Mestel Safety, part of the OceanReefGroup, whom, under the brand OCEAN REEF manufactures full face masks for snorkeling and scuba purposes and through the brand Safety Protection Equipment, manufactures gas masks. 

The Filed Patent is for an adapter to connect full face snorkeling masks to filters with the aim of transforming the snorkeling mask, into a personal protection mask. Its name is APA: ARIA Protection Adaptor, since our snorkeling mask line is called ARIA.

OCEAN REEF already has more than 1.25 million full face snorkeling masks in the homes of customers around the world, plus good inventory through our worldwide dealers and our US and Italian warehouses.

The adaptor would offer another possible solution and help providing alternative PPE in a time of dire need.

Mestel Safety SRL-Ocean Reef Group received from the Italian National institute for insurance against industrial injuries, INAIL, the extraordinary validation for the Personal Protective Equipment of third category constituted by the Aria/UNO snorkeling mask assembled with the APA adaptor (Aria Protection Adaptor) and the P3 filter, certified under the EN136: 2000 standard.

The use of the adaptor is at the discretion of each individual and should only be used when other approved PPE are not available.

How Does It Work

The APA with a certified and properly installed filter, can assist in the filtration of breathable air and reduce the inhalation of contaminants.

APA adaptor has a non-return valve, so only fresh air passes through the filter and only filtered air enters into the mask.

The exhausted air has a different channel and it is expelled from the lower part of the mask, where another non-return valve ensures air will only exit from there.

(In the open source project is also available the design of  the Exhausted Valve Cover 22mm: an another adaptor made to filter the exhaled air).

Our snorkeling masks breathing technology is patented and certified. The airflow and the CO2 levels are tested and safe.

The converted mask is a reusable and cleanable full-face shield.

 

Configurations

The adaptor kit allows to connect most common filters to the mask.

APA is compatible with all the filters with EN 148-1 connection.

RD40-22mm can be screwed on APA to connect HEPA filters (40mm 1/7″ threaded outlets).

 

All the Ocean Reef mask are compatible with our optical lens support.

Lenses are available in different graduation.

 

To filter exhausted air, wear a surgical mask on ARIA or install a filter with the exhaust valve cover.

FAQ

Is it reusable?

Masks and adaptors can be immersed in boiling water to sterilise.

We also tested in dishwashing machines with common  cleaning product (tablets) at 70°C (158°F) for up to 1 hour. Colours maybe lost but items were fine and functional.

Filters cannot be reused.

 

Where can I order the Adaptor?

The adaptor can be ordered through our OCEAN REEF dealers and distributors (European and American) or our head offices in Italy and US for hospitals and institutions. If you can’t find a suitable way to purchase, contact us. 

How long does the filter last?
Can I download 3D files?

Yes, click here.

We ask for a licensing agreement to be signed. 

 

Is it protecting against COVID19?

The adaptor and masks  alone do not provide any more than a physical barrier without any filtering abilities. So, no. Depending on type of filter, it, provides filtration of breathing air. We cannot  test any certified effectiveness against COVID19.

Does it adapt to all OCEAN REEF masks?

Yes, APA works with all OCEAN REEF manufactured masks. We also have 3D files for other famous brand and can make for more, but you will still require gasket and mushroom valve as explained in 3D Files page.   

CLINICAL INFORMATION

Medical Experiences

We are using this new patented filtering mask. It is very innovative and much more safe than surgical masks. We use it, above all, for dental procedures or digestive endoscopy treatments. 

Santagostino Medical Center (Milan, IT)

My anesthsia group bought around 200 of your masks to be repurposed for us. They are actually really comfortable and feel safer than the n95/face shield.

Rebecca Fosket MS, CRNA (Chicago, USA)

We have to protect ourselves from a virus we have very little information on. By wearing this, I’m decreasing of contracting or giving the virus to someone else. I can’t accidently touch my face and the attached viral filter ensures my air is purified. I clean it after every patient I see, easily. With the lack of WHO advised PPE, this is a cheaper and efficient alternative. I have to thank Avendale Limited for providing me the 3d printed adaptor.

Tests & Evaluation

On May 27 2020 Mestel Safety SRL-Ocean Reef Group received from the Italian National institute for insurance against industrial injuries, INAIL, the extraordinary validation (protocol: INAIL.72000.27/05/2020.0016170) for the Personal Protective Equipment of third category constituted by the Aria/UNO snorkeling mask assembled with the APA adaptor (Aria Protection Adaptor) and the P3 filter, certified under the EN136: 2000 standard. This validation complies with the Italian Law art.15 comma 3 decreto-legge Governo Italiano 17 marzo 2020, n.18 Emergenza COVID – 19.

The use of the adaptor is at the discretion of each individual and should only be used when other approved PPE are not available.

 

Decontamination

After some preliminary tests carried out on Aria 19, APA and RD 40 adaptors, the following sanitization procedures are proposed.

They are based on recommendations from CDC, OSHA, the National Academy of Science and many hospitals in Europe, Canada, and USA. All the Aria 19 mask and adaptors are functional and seal well after each sanitization process.

 

  • Remove any filter connected to the adaptor prior to sanitization.
  • NEVER use any solvent, cleaner or abrasive product to clean the Aria 19 Mask, the RD40 and the APA Adaptor.
  • Do not sanitise a mask+adaptors protection system that is clearly damaged.
  • Be careful do not deform the Aria 19 Mask, the RD40 and the APA Adaptor during sanitization as it could negatively impact its fit.
  • Follow one of the methods below.

Treatment in Diluted NaClO (bleaching solution)

1. Place the Aria 19 mask, the RD40 and APA adaptors in a commercial solution of NaClO-sodium hypochlorite (dilution: max 2.5-3% vol/vol) for 5-10 minutes.

2. Possibly, each mask and adaptors should not overlap or cover the other ones.

3. After sanitization, remove carefully the mask and the adaptors from the solution, rinse deeply under fresh water just to remove all the hypochlorite residuals and allow the perfect drying in a safe and no contaminated environment.

4. Maximum allowed sanitization cycles: 120

Treatment with Sanitising Wipes

1. Clean Aria 19 mask, the RD40 and APA adaptors with commercial alcohol based, benzalkonium chloride or hypochlorite based wipes.

2. After sanitization, remove the wipes, disposing them properly, and allow the perfect drying in a safe and not contaminated environment.

3. Maximum allowed sanitization cycles: 400

Treatment in Boiling Water (suggested only for domestic use)

 

1. Place the Aria 19 mask, the RD40 and APA adaptors in boiling water for 5-10 minutes.

2. Possibly, each mask and adaptors should not overlap or cover the other ones.

3. After sanitization, remove carefully the mask and the adaptors from hot water, allowing the perfect drying in a safe and not contaminated environment.

4. Maximum allowed sanitization cycles: 160

Filter Sanitization

1. Clean the filter with commercial alcohol based, benzalkonium chloride or hypochlorite based wipes.

2. After sanitization, remove the wipes, disposing them properly, and allow the perfect drying in a safe and not contaminated environment.

3. Maximum allowed sanitization cycles: 500

Treatment in Diluted Ethanol

1. Place the Aria 19 mask, the RD40 and APA adaptors in a commercial solution of ethanol (dilution: 3-5% vol/vol) for 5-10 minutes.

2. Possibly, each mask and adaptors should not overlap or cover the other ones.

3. After sanitization, remove carefully the mask and the adaptors from the solution, rinse deeply under fresh water just to remove all the alcohol residuals and allow the perfect drying in a safe and not contaminated environment.

4. Maximum allowed sanitization cycles: 120

Treatment with Medical Disinfectants

1. Clean Aria 19 mask, the RD40 and APA adaptors with commercial medical disinfectants based on

benzalkonium chloride, ethanol or chlorhexidine for 5-10 minutes.

2. Possibly, each mask and adaptors should not overlap or cover the other ones.

3. After sanitization, remove carefully the mask and the adaptors from the solution, rinse deeply under fresh water just to remove all the alcohol residuals and allow the perfect drying in a safe and not contaminated environment.

4. Maximum allowed sanitization cycles: 400

Treatment in Dishwasher (suggested only for domestic use)

 

1. Place the Aria 19 mask, the RD40 and APA adaptors in a dishwasher for one (1) hour at 70°C using

dishwasher soap. The dishwasher should be sterilized prior to use. They should be the only objects in the dishwasher.

2. After sanitization, remove the mask and the adaptors from the machine, allowing the perfect drying in a safe and not contaminated environment.

3. Maximum allowed sanitization cycles: 160

Upon completion of the cycle, the filter, the Aria 19 mask, the RD40 and APA adaptors must be stored in a closed PE bag ready for the next use in a dry and cool place. If one of them appears visually damaged or soiled, it should be discarded. Any mask and/or adaptors that has exceeded the sanitization cycles should be discarded as well.

Please note that successful completion of the chosen method and cycle signifies appropriately sanitised filter, Aria 19 mask, RD40 and APA adaptors.

Please note that this protocol is not formally approved, and each hospital should consult their EH&S officers or infection disease specialists for a standard operating procedure.

Instructions 

Filters

Our adaptors and connections are designed with the 40mm 1/7″ threading standard in mind. That is the same threading of most Gas Masks, as our SGE series masks (visit our website). While we may provide Multipurpose and P3 Filters, please note that any filter with that threading is compatible with our APA and EPA designs. 

Different filters have different capabilities. You will find a lot of information searching on the Internet what filter best suits your needs.

This does not guarantee any performance as filters are intended for use with certified products and/or have never been tested by official notified body for use on a Full Face Snorkeling Mask. 

What filters should I use with APA?


40mm threading canister Flters EN 148-1 we suggest to use with our product are: 

MESTEL SAFETY PROTECTION EQUIPMENT P3 filter (SKU M40040-SP, technical sheet)

Scott Safety Pro2000 P3 Filter

Arco P3 40mm DIN Screw Thread Filter

Mira safety Particle P3 

and many more.

We are not affiliated with other aforementioned manufacturers. There are many more that provide certified, similar products. 

What filters should I use with RD40-22mm?

This piece connects rd40-22mm inlets to 40mm 1/7″ threaded outlets. With this, you can connect an APA or EPA, or SGE Gas Masks and other PPE that use the NATO 40mm standard, to rd40-22mm devices such as hydrophobic bidirectional filters, or similar that can commonly be found in hospitals.

ISO 5356-1 compliant bacterial and viral removal filters we have considered for application are following:

PALL BB50T : specs HERE.

Medtronic DAR™ Adult − Pediatric Electrostatic Filter : specs HERE.

and many more.

We are not affiliated with any of these manufacturers. There are many more that provide certified, similar products. 

We have learned that these hydrophobic bidirectional filters have a very low breathing resistance and have excellent performances in protecting from contaminations, as well as having a very long duration. Here is an example of product specifications. We are in no way related to filter manufacturing, maker or have tested such equipment.

The rd40-22mm adaptor can be screwed on the APA. The hydrophobic bidirectional filter can then be inserted into the female connection.

These adaptor’s designs are also available for download.

Moreover, until testing and certification is not completed we cannot guarantee that the complete equipment is able to satisfy requirement to qualify as protection device and safety of the product.  

We are able to adapt our technology also to other masks. Please contact us if interested.

Can I use my bayonet filter with a 40mm 1/7" filter connection?

Yes, there are commercially available adaptors of very serious manufacturers HERE (for example).

Moreso there are also 3D print alternative connectors. You can find some options HERE as kindly reported by Junior P (unknown name). 

How long does the filter last?

The service life of a respiratory filter depends on its size and on the conditions of use. Factors affecting service life:

• concentration of the contaminants

• combination of the contaminants

• air humidity

• temperature

• duration of use

• breathing rate of the user

Since the service life is influenced by many factors, it is not possible to give an estimated service life.

The end of service life is generally recognizable by:

• gas filters by a noticeable taste or smell of the

contaminant

• particle filters by an increased breathing

resistance

• combination filters a noticeable taste or smell

and/or an increased breathing resistance
