Is your Johnsburg air filtered through a clean cabin filter?

Heading out for a drive? Wanna get some fresh air? You can roll those windows down and let the wind blow through the car as you drive. But how fresh is that air (hopefully, not bad here in Johnsburg)? Then again, if it’s cold or it’s raining, you may want the windows up.

With the windows up, you have a choice what air you want to breath. You can adjust the vent so the air inside the cabin is recirculated. Or you can set the vent so outside air enters the cabin. In either case, how fresh is that Johnsburg air?

If you’re recirculating the air, with every breath you take, you are recirculating your own carbon dioxide through your respiratory system. YUK! And not the healthiest idea.

Other than the air that enters your car’s cabin through the window, the air that is pulled through your vents by the cabin blower has a potential advantage over the air coming in through the windows; there is a line of defense to ensure you and your loved ones are breathing fresh air.

Fresh air and your cabin filter

You have numerous filters in your car that can include:

The engine air filter
The oil filter
The Crankcase breather filter
The air dryer filter
The oil vapor filter
The vapor emission filter
And more …

One other filter you’ll find in your car is the cabin air filter. The oil filter filters the oil as it flows through the engine. The air filter filters air as it enters the engine. The vapor emission filter filters fuel vapors from the atmosphere. The cabin air filter filters the air that enters the inside of your car.

Of course, the air that it filters is the air that enters through the vents. In the case of recirculated air, it filters the air as it passes out of the cabin and then back in.

It’s amazing to see just how dirty a cabin air filter can get. It’s disgusting to think that we’re breathing air that ‘filters’ through a filter that dirty. But, when replaced regularly, the cabin air filter ensures that you’re breathing the cleanest possible air inside your car.

Even if you’re cabin blower is turned off, if outside air is coming through the vents, it’s going through the cabin filter, dirty or clean.

Johnsburg air isn’t bad. But a clean cabin filter makes it even better.

Is your antifreeze safe from freezing this Richmond winter

You still have time to have it checked Well, there’s no denying it – winter tends to get chilly here in Richmond. We have to deal with snow and ice on the roads, scraping the same off our windows and windshield, and staying warm while we drive. Of course, you had your antifreeze checked before winter rolled into town. What?! You didn’t have your antifreeze checked before winter clamped down on Richmond? So, how’s your antifreeze doing? If you haven’t had it checked, there’s really no way of knowing, is there? This car has overheated in the middle of a Richmond winter. But, on the other end of the spectrum, the antifreeze can also freeze if it's not up to its job. Hopefully, you haven’t had a serious problem with your antifreeze already. If you did, you’d probably know. When antifreeze fails, it’s a potentially catastrophic condition for your vehicle’s engine. You could have hoses that have burst because of freezing antifreeze. Worse than that, your engine block may have crac...

Blocks of ice falling from cars in McHenry could cause accidents or damage

We’ve all seen those blocks of snow falling from behind the rear tires of a car when the snow rolls into McHenry . Fortunately, they’re just packed snow that will disintegrate under your vehicle’s tires as you simply drive right through them, right? Don’t count on it. Those blocks of snow are often packed so tight, condensed by the thaw-and-freeze cycle, that they’re anything but oversized snowballs . They’re often more like boulders. Hit one of those blocks and the collision between the block and one of your tires could send you careening off the road or into oncoming traffic. In some cases, they’re so solid you could pound them with a sledgehammer with little effect. They truly can represent a serious road hazard. The problem is that it’s difficult to tell how solidly they’re packed when you see them on the road, left their unwittingly by another driver. Either way, your best bet is to try to avoid them. But you want to be careful dodging blocks of ice in the road, too. You need...

Get out to McHenry Music Festival for a good time and music near to home

Some folks here in McHenry will load up the car and head out to Red Rock Amphitheater near Denver to see a show. Some will go to the MSG Sphere near Las Vegas. Some will go to the Bonaroo Festival Concert to see a show. That’s quite a bit of driving and you’d better make sure your vehicle is up to the trip. What happens, however, if something goes wrong – if your vehicle breaks down while driving there or back? What happens if the show is canceled, as happened this year with the Bonaroo Festival? We’re talking about some serious inconvenience, aren’t we? Wherever you go, whether your driving to Colorado, Nevada, Tennessee or anywhere else in this continent, you want to perform your due diligence and make sure the vehicle is up for the trip before you go. And it doesn’t really matter if you’re driving somewhere to see some live music or for any other purpose. A breakdown can be costly and may put you at the mercy of weather conditions or nefarious characters that come across you while y...
