"I remember standing in my son's room one night, watching him sleep. Everything looked peaceful. Then I looked at the carbon monoxide detector on the wall and realized I was putting all my trust in a tiny green light that couldn't tell me what was actually happening in the air. That thought stayed with me all night. The next morning, I ordered EverShield. Now I check the screen before bed every evening. Seeing that '0' has become part of my routine—and honestly, it's the last thing I look at before I turn off the lights. As a dad, you can't protect your family from everything. But you should never have to guess whether the air inside your own home is safe."

Don't Become Another Headline.

Carbon monoxide danger

Carbon monoxide doesn't give second chances.

Every year, hundreds of American families lose someone to accidental carbon monoxide poisoning—many while they sleep.

The most heartbreaking part? Many believed they were protected. Their detector was on. The green light was glowing.

But carbon monoxide doesn't have a smell. It doesn't have a color. It doesn't make a sound.

By the time you know it's there... it may already be too late.

Every Second Matters.

Traditional Detectors Wait. EverShield Doesn't.

Introducing EverShield™ CO & Gas Detector

EverShield is a professional-grade CO & gas detector that helps you monitor carbon monoxide, natural gas, and propane in real time—starting from 0 PPM, so you can see rising danger before it becomes an emergency.

It's simple enough for anyone to use. Just plug it into any standard outlet and you're protected in under 20 seconds. No tools. No wiring. No electrician.

Keeping an EverShield in your home isn't just another safety upgrade. It's one of the smartest decisions you can make for the people you love.

Because carbon monoxide doesn't warn you. EverShield does.

Designed With Firefighters. Built To Save Lives.

EverShield was developed alongside firefighters who witnessed the same heartbreaking reality over and over again—families with "working" detectors who never got the warning they needed.

UL 2034 Certified — Built to meet North America's strictest carbon monoxide safety standards.

"EverShield Showed 32 PPM. My Old Detector Showed Nothing."

"We'd trusted the same detector for years. The green light was always on. It beeped every time I tested it, so I never questioned it. The first night I plugged in EverShield, it showed 32 PPM near our furnace. My old detector? Still silent. Still showing green. That was the moment I realized there was a difference between owning a detector... and actually knowing what was in the air my family was breathing."

"Now I Know My Grandchildren Are Safe Here."

"Every weekend my daughter brings the grandkids to stay with me. The moment they walk through my front door, they're my responsibility. For years, I trusted the detector on my wall because I didn't know there was another option. EverShield changed that. Now, before everyone goes to bed, I glance at the screen, see everything is safe, and sleep peacefully knowing the people I love most are protected. There's no greater feeling than knowing Grandma's house is still the safest place they can be."

"I Bought One for My Home. Then I Bought Two More for My Parents."

"After installing EverShield in our home, there was no way I was leaving my parents without one. My dad is 76, and they had been relying on the same detector for years. The green light was still on, but I had no idea if it was actually protecting them anymore. I ordered two more EverShield detectors the same day. Now I don't wake up at 2 AM wondering if they're okay. It's one of the best decisions I've ever made."

"I Bought Five—One for Every Home in My Family."

"I kept one for myself and ordered four more for the people I care about most. My children all have families of their own now, and this was the one gift I knew they would never buy for themselves—but one they should never be without. I hope they never need EverShield. But if that day ever comes, I'll have peace of mind knowing I did everything I could to help protect them. Sometimes the best way to say 'I love you' is making sure the people you love are safe."

"My Husband Thought Our Old Detector Was Enough."

"For years, my husband kept saying, 'The detector works. Why replace it?' Then I showed him how traditional detectors can stay silent while carbon monoxide levels continue rising. We ordered EverShield that same night. Now, before we go to bed, he checks the display himself. Funny how the person who didn't think we needed it is now the one who refuses to sleep without it."

"I'm 73... And I Didn't Need Anyone's Help."

"I installed every EverShield detector in my home by myself in less than an hour. No ladder. No tools. No waiting for my son to come over and do it for me. Now, whenever I glance at the display, I know exactly what's happening inside my home. At my age, that kind of confidence and independence means everything."

"One of the Most Important Things I've Ever Bought."

"I'm 78 years old and I've lived alone since my wife passed away. Some nights I'd find myself wondering, 'If something happened while I was asleep... would anyone even know?' Now, every night before bed, I look at EverShield's display, see that reassuring '0,' and turn off the lights with confidence. I may live alone... But I never feel unprotected."

"It Found What My Old Detector Missed."

"We already had detectors throughout our home. I honestly bought EverShield just to compare. Within the first week, EverShield showed elevated carbon monoxide levels. Our old detectors? Silent. It turned out we had a small problem with our furnace that needed immediate attention. We have four kids. I don't even want to think about what could have happened if we had never known."

Questions From Homeowners

Most detectors only show a green light — which stays on even when the sensor is dead. They don't alarm until 70 PPM, which is AFTER 1-4 hours of exposure. EverShield shows you real-time levels from 0 PPM on a digital display. You see the truth, not a light that lies.
No. EverShield uses professional-grade electrochemical sensors — the same type used in industrial settings. They detect real threats, not toast or shower steam.
EverShield is a 4-in-1 detector. It monitors carbon monoxide, natural gas, AND propane, plus temperature and humidity. This is a critical distinction. Most cheap detectors from the hardware store only detect CO. If your stove leaks natural gas, your furnace has a propane leak, or your water heater line is compromised, those detectors stay completely silent. EverShield catches all three gas threats in real-time, with PPM readings on the display starting at 0. One unit. Complete protection. No gaps.
EverShield plugs into any standard wall outlet, no ladder, no tools, no electrician. 30 seconds and you're protected. For placement, focus on two priorities: near gas appliances (furnaces, stoves, water heaters) and in hallways outside bedrooms where your family sleeps. EverShield's sensors are calibrated to detect all three regardless of outlet height. Most families start with one near the furnace/water heater, one in the kitchen near the stove, and one in the hallway outside bedrooms. The 4-Pack covers most homes completely.
No. Plug it into any eye-level outlet. That's it. Takes 30 seconds. No ladder, no tools, no electrician.
One per floor + near bedrooms + near gas appliances (furnace, water heater, garage). Most homes need 4. Apartments typically need 2.
Yes! EverShield is perfect for people who live alone. It watches 24/7 and will alert you to danger even while you're sleeping. Many of our customers are seniors who live independently and wanted peace of mind.
You're covered by our 100-Day "Sleep in Peace" Guarantee. If you're not satisfied for any reason, we'll refund every penny. No questions. Plus, the Lifetime Guarantee means we replace it free if anything ever goes wrong.
Hardwired means it runs on electricity — but the SENSOR inside still expires after 5-7 years. The green light stays on even when the sensor is dead. EverShield plugs in and shows you a real number, so you always know it's working.
