Very limited amount of 'invisible' filters coming soon. Check out https://www.youtube.com/watch?v=mmJmnf-4ukU for what they are. More details coming soon.
The FilterPro site uses Paypal but you don't need a Paypal account to check out.
Select 'pay with card' or 'check out as guest' and you will be able to check out using any card.
Paypal is just the payment processor.
All the best for 2024
