Dust mites are microscopic pests that live in carpet and feed on shed human skin. The EPA and the American Lung Association list them as an asthma trigger. Professional hot water extraction removes soil and dust from carpet and leaves it dry in 2–4 hours. It is not a medical treatment, and Xtreme Cleans does not promise allergy or asthma relief.
Xtreme Cleans is a carpet cleaning company serving 12 Maryland counties plus Baltimore City. This guide separates what carpet cleaning does from what health agencies recommend for dust mite control, so a household with allergies can plan both. The wider picture is in carpet, allergies and asthma.
Does professional cleaning help with dust mites and allergens?
Professional hot water extraction removes soil and dust from carpet. It does not remove every dust mite allergen from a home, and no study cited here shows that cleaning relieves asthma. Xtreme Cleans makes no allergy-relief promise.
A dust mite is a microscopic pest that feeds on dead human skin cells and thrives in warm, humid settings. The American Lung Association says dust mites live in bedding, mattresses, upholstered furniture, carpets and curtains. A dust mite allergen is the protein material from those pests that triggers a reaction in a sensitive person. The EPA adds that household dust, which gets stirred into the air by normal activity, can contain many biological contaminants.
Xtreme Cleans uses hot water extraction on residential carpet, and the hot water extraction guide covers it in full. The crew vacuums the carpet first, so loose dust leaves before the water goes down.
The research on mite control is cautious. A 2008 Cochrane review of mite-control measures in the homes of people with mite-sensitive asthma concluded that chemical and physical methods aimed at reducing exposure to house dust mite allergens cannot be recommended. The same literature gives the practical advice that health agencies repeat, and the table below sets it out.
| Source | What it recommends for dust mites |
|---|---|
| US EPA | Keep indoor humidity between 30 and 50 percent; routinely vacuum carpets and fabric-covered furniture; use allergen-proof mattress and pillow covers |
| CDC | Vacuum regularly with a HEPA-filter vacuum; wash bedding weekly; keep relative humidity around 30–50% |
| American Lung Association | Keep humidity below 50 percent; vacuum weekly with a HEPA filter; wash bedding in hot water once a week |
| Carpet and Rug Institute | Vacuum at least once a week; deep clean professionally every 12 to 18 months |
Professional cleaning fits the last row. It is a periodic deep clean on top of weekly vacuuming, not a replacement for humidity control or bedding care. A person with asthma or an allergy should ask a doctor what to do about dust mites.
Is carpet cleaning safe around allergens?
Xtreme Cleans cleans carpet with Green Seal GS-37 certified chemistry and finishes every clean with a rinse. Tell the office about any allergy, asthma or chemical sensitivity when you request the quote, and ask a doctor whether to be home during the visit.
Three practical points apply to a household with allergies.
- Pets and people: pets go in another room or in a crate for the visit. Shoe covers and floor protection go on at every visit.
- Access: the customer does not need to be home if the crew can get in with a key or door code. The truck needs parking close to the entrance.
- Furniture: the crew does not move furniture. The customer moves what they want cleaned underneath. Heavy or fragile items such as televisions, electronics and antiques are skipped.
Mold is a separate allergen, and it is outside this service. Xtreme Cleans declines carpet with visible mold and refers it to a mold remediation professional. See why mold is outside this service. Flooded or water-damaged carpet goes to a water-damage restoration professional, because Xtreme Cleans does not offer water extraction.
Once the visit is planned, the next question is timing: how long the carpet stays unusable.
How soon can the room be used again?
Carpet is dry 2–4 hours after cleaning, and a typical 3-area visit takes 1–2 hours on site.
The 2–4 hour dry time belongs to truck-mounted hot water extraction. What happens during a visit is laid out in four steps, and the preparation guide lists what to do beforehand.
Dust mites thrive in warm, humid settings, so room humidity stays a separate job from the cleaning visit. The air quality guide covers ventilation and humidity after a clean. The target is the same before and after: the EPA and CDC give 30 to 50 percent. A humidity gauge from a hardware store shows the reading, and the EPA recommends one.
What products do you use, and are they certified?
Xtreme Cleans uses Green Seal GS-37 certified cleaning chemistry, and every clean ends with a rinse that removes cleaning residue. Technicians are trained in house and background-checked.
The full product and certification details are in the air quality guide. GS-37 is a statement about the chemistry, not about dust mites.
Xtreme Cleans does not claim that the service kills dust mites. The EPA-funded Wright State project found that killing D. pteronyssinus in laundry took hot water held for more than 30 minutes, and that warm water killed less than half of the mites. That finding concerns washing bedding and clothes. It is the reason bedding care sits beside carpet care in the table above.
How does Maryland humidity affect dust mites in carpet?
Indoor humidity above 50 percent favors mites. The article on Maryland humidity and carpet drying covers how Maryland's humid months affect drying, and the spring pollen season checklist covers the seasonal side.
Humidity is the control the EPA-funded research measured. In homes that held humidity below 51 percent, dust mite allergen fell from 17.5 to 4.0 micrograms per gram of dust over the study. Air conditioning and a dehumidifier are the usual tools in humid months. A deep clean does not change the humidity in a room.
How much does carpet cleaning cost in Maryland?
$199 for 3 areas, with stairs and pet-urine treatment quoted separately.
See room-by-room pricing for how Maryland carpet pricing is built, and the breakdown by area for what drives the number.
How often should carpet be cleaned?
The Carpet and Rug Institute recommends a professional deep clean every 12 to 18 months and weekly vacuuming at minimum. More foot traffic means more vacuuming.
The often-clean guide covers what else changes the schedule. To book a carpet cleaning in Maryland, use the quote form below. Describe the carpet and mention any allergy or sensitivity in the household. Service runs Monday to Sunday, 8 AM to 10 PM.
Frequently asked questions
Can carpet cleaning kill dust mites?
Xtreme Cleans does not claim that the service kills dust mites. In the EPA-funded Wright State research, killing the dust mite D. pteronyssinus in laundry took water at 122°F (50°C) held for more than 30 minutes, and that finding concerns washing bedding and clothes. Hot water extraction removes soil and dust from carpet.
Should you wash bedding as well as clean carpet?
Yes. Bedding care is a separate job that carpet cleaning does not replace. The CDC advises washing bedding weekly, and the American Lung Association advises washing bedding in hot water once a week.
What humidity level discourages dust mites?
The EPA and CDC give 30 to 50 percent relative humidity, and the American Lung Association says to keep humidity below 50 percent. A deep clean does not change the humidity in a room.
Does professional carpet cleaning replace vacuuming?
No. It is a periodic deep clean on top of weekly vacuuming. The Carpet and Rug Institute says to vacuum at least once a week and to deep clean professionally every 12 to 18 months.
Do dust mites live in carpet?
Yes. The American Lung Association lists carpets, along with bedding, mattresses, upholstered furniture and curtains, as places dust mites live. Dust mites feed on dead skin cells and thrive in warm, humid settings.
