Frequently Asked Questions:


Who is within this company?

KN95RespiratorMasksForSale.com is co-founded by Dr. Jay Park MD.  He is a board certified Emergency Medicine physician in NYC, who has been working with an NGO vetting non-traditional PPE suppliers and products from China.  Witnessing the mass chaos in the marketplace, he used his connections to set up a factory direct opportunity for small and mid-size enterprises who frequently miss out on the wholesale pricing for large enterprises.  He calls it "Groupon for PPE."


How do I know the quality of these respirators?

Dr. Park has become an expert on vetting non-traditional PPE, as he commonly gets requests from WSJ, NYT, Buzzfeed and many others.  He has written extensively on the topic of KN95 and the PPE problems from China.
He has had three of his colleagues die from COVID-19.  Getting quality PPE to his friends and co-workers has become a mission to him. 
Through PPEConnector.com, we have gone through a thorough an extensive vetting process to find trusted suppliers who are offering authentic PPE at reasonable current market prices. In each of the product listings, we reveal the name of the company and the link to CDC testing or CDC authorization page.  We believe in offering only PPE that has been tested to be safe in USA. 


How do I know that YOUR respirators are not counterfeits?

The best way to get authentic PPE is to buy them at the factory.  We have extensive connections that will buy directly from the factory or an authorized trusted distributor of PPE in China.  We purchase directly from the closest source to the factory to minimize the risk of counterfeits. We also use a trusted partner in China to facilitate the shipping.


The seal from my respirator box is broken. How do I know that this is not fake?
We have had several complaints from our customers that the factory seal is broken. Your respirators travel from China to your home.  Sometimes, they are delivered directly from China.  Other times, they are delivered to our warehouse in San Diego, then to your home. The factory seals can break anytime during the transportation process due to the duration of the travel and your box being mishandled during transportation.  If your seal breaks, then please ship it back to us and we'll replace your respirator.  However, we cannot guarantee that your next box will have a factory seal intact.  We can however assure you that you are getting authentic respirators from the Chinese factory and that the seal was intact pre-shipment.  


I got respirators from another company.  Can you tell me if my respirators that I purchased from someone else are authentic?

We can provide resources for you to vet them yourself.  Please read through the extensive PPE article collection written by Dr. Park below.  Your respirator is only as good as your source.  There are even reports of fake 3M respirators in the marketplace right now.  It's NOT only the manufacturer brand name that you can count on, but the distributor of your PPE that you need to vet and trust.

How can you price these respirators so low?

We have taken the best suppliers from PPEConnector.com and decided to offer factory discount pricing to everyone else who can't afford to buy 100,000 to 500,000 minimum quantity orders. We buy in bulk and pass on this savings to you. We trim costs in every single way possible including shipping. 


Why is the shipping time so long?

Good news. We used to ship directly from China to the USA. Now we have shipment within the USA and can ship to you via USPS priority mail. Shipping now takes around 3-4 business days.


Do you have to pay import duties or taxes?

No.  Our courier has given us this rule from China:
"The recipient is an individual: self-use is acceptable. Formal declaration is required if the declared amount is more than 800 USD or more than 100 masks or plastic gloves."
However, import rules are constantly changing and we can not guarantee that your country will NOT charge an import tax or duty.


Do you accept returns?

Respirators are personal use products.  If there are damages due to shipment or there is a product defect, then YES we accept returns. Due to hygienic standards, we are unable to accept returns for any products that were opened or used.  We are unable to accommodate changes or cancellations on any orders after shipment.  Please contact us if there are damages to the respirators. Please note that 3M factory seals are poorly designed and can break anytime during the transit from China to our US warehouse to your home. If it breaks in transit and you want a replacement box with an intact seal (we cannot guarantee that the second box will have a seal that will be intact upon arrival), then YOU are responsible for the return shipping. 


Do you give back to charity?

Yes.  We give back 10% of the gross revenue back to charity.  This means that when you spend $100 with us, we give $10 to charity.  We know that many charities are suffering during this crisis and it is our mission to continue contributing to organizations who will support the public long after COVID-19 is gone. 


Are you an authorized distributor of Honeywell or 3M?

No we are not an authorized distributor.  We are purchasing our respirators from the factory or an authorized distributors in China and shipping them to you. This is a copy of the legal opinion about the adjusted US/China import policy about respirators due to COVID-19.


Why should I trust your company?

If you can't trust a company co-founded by an actively practicing board certified Emergency Medicine physician in NYC named Dr. Jay Park who has

then we wish you the best in finding authentic PPE elsewhere.
