Alyssa Milano hits back at trolls after they slam her crochet mask and tells them it has a carbon filter attached to it

She's not afraid to call out haters when they troll her online. 

And Alyssa Milano did just that when Twitter users called her out for her 'useless' face mask that was crocheted - and therefore had holes throughout. 

But the 47-year-old wasn't having a bar of it, telling haters that she inserted a protective filter underneath. 

'Mask has a filter in it for f**k's sake!' Alyssa Milano called out haters on Saturday after they slammed her for her unprotective face mask 

It all started after Alyssa shared a family selfie of herself, husband, Dave Bugliari, 39, and their kids, Milo, eight, and Elizabella, five, wearing their masks ahead of an outing. 

And while Dave and the kids all sported different styles that covered their faces, many weren't too impressed with the actress' choice, with her skin able to be seen through the crocheted design. 

One hateful user Tweeted: 'So knitted face mask are going to protect you from Covid-19 Alyssa Milano you are a special kind of stupid #alyssamilano.' 

Proving her case: Alyssa went as far as to show the filters she was using behind her mask for extra protection 

Alyssa hit back, writing: 'Mask has a filter in it for f**k's sake. A carbon one. My mom makes them. #WearAMask,' she wrote adding the emoji of the face with rolling eyes. 

The Charmed star went as far as to share a screenshot of the 100 pack of filters she had purchased to ensure full protection amid the COVID-19 pandemic. 

She also Tweeted: 'Assholes, mask has a carbon filter in it. So, yes, it might be crochet but totally safe. #WearAMask.' 

Not impressed: Many took to Twitter to call out Alyssa's crochet face mask 

And while many accepted her response, others claimed to still see her skin through the mask so concluded there was no filter used in the photo. 

'There is zero filter in that. We can see through it you dunce,' penned user @JHWalz32.  

Filters have become increasingly effective after research has shown up to 50% of those with COVID-19 don't show any symptoms. 

There have been over 1.65 million confirmed cases of coronavirus in the United States since the start of the pandemic.
